(written from a Production point of view)
Babylon 5 is a multi-Emmy Award winning and nominated American science fiction television series created and produced by J. Michael Straczynski for Warner Bros. Developed, produced and aired in the same period of time as Star Trek: Deep Space Nine had been, resulted in back and forth recriminations of plagiarism, leading up to a fierce competition between the two franchises at the time.
The primary series, which ran from 26 January 1994 to 25 November 1998 after its pilot episode was broadcast on 22 February 1993. It was the first truly successful American futuristic, space-oriented science fiction television series outside Star Trek and therefore the first serious contender for the Star Trek franchise, which until then had pretty much the run of the science fiction television landscape when it started its rebooted run in 1987 with Star Trek: The Next Generation. Like Star Trek, there have been several attempts to create viable spinoff properties, including six made-for-TV movies and the short-lived series Crusade, featuring Daniel Dae Kim, Marjean Holden, and Tracy Scoggins. Enjoying a considerable measure of success while the original source series was being produced and aired, the franchise eventually faded into obscurity due to a combination of intentional sabotage by TNT, poorly considered money-saving maneuvers by Warner Bros. (including but not limited to the decision to save $5,000 per season which in the process made it also impossible to produce a later high definition version of the show with recomposited wide-screen versions of effects shots, after digital assets were lost as the studio was unwilling to pay for their upkeep), as well as internal studio politics. The show continues to be available on Standard Definition DVD and has a cult following, but has not been syndicated since the early 2000s, making it hard for potential fans to discover and preventing a fan driven comeback such as was enjoyed by Star Trek.
The series was widely acclaimed for its ambitious writing, much of it by Straczynski himself, who endeavored to tell a complex, predetermined epic story arc, in the form of the Shadow War, over the series' entire run, as opposed to the episodic (or two-part episodes at the most) story format until then employed for science fiction television series. It thereby convincingly dispelled the hitherto universally held belief by Hollywood studios that television audiences lacked the attention span to remain interested in a science fiction series format thus conceived. (see also in this regard: Battlestar Galactica: Reception and demise) In service of that goal, the show had an innovative visual style, taking advantage of advances in computer animation to create spectacular fantastic visual effects (VFX) on an economical budget, most notably computer generated imagery (CGI), pioneered by Foundation Imaging, who later also provided VFX for the Star Trek franchise. The use of CGI in the series was a definitive breakthrough in creating VFX for television, much as the movie Jurassic Park was for cinema; it went on to become the primary technique.
Another production company of note was the prosthecics and makeup special effects (SFX) company Optic Nerve Studios, Inc. which was contracted in 1993 to serve the original Babylon 5 series. Turning out to be a fruitfull collaboration, winning the franchise several Emmy Award nominations and wins in the various makeup categories and therefore putting the novice company firmly on the map in the industry, the company was retained for the remainder of the entire run of the franchise. Restructured into Alchemy Studios by its then owners Glenn Hetrick (who himself had worked as an industry novice on the tailend of the Babylon 5 franchise while employed by the company) and Neville Page, the company was in 2017 contracted for similar services on Star Trek: Discovery, for the re-imagined Klingons in particular, likewise winning the series its first 2018 makeup Emmy Award nomination.
The series starred Bruce Boxleitner, who later went on to make an appearance on Heroes with Zachary Quinto, and Mira Furlan, who later had a recurring role on J.J. Abrams's Lost with Terry O'Quinn, Daniel Dae Kim, and others. The series also featured numerous Trek alumni in the cast as important recurring or regular characters, most notably Walter Koenig, Andreas Katsulas, Bill Mumy, and Patricia Tallman. Michelle Forbes' ex-husband Ross Kettle also did an episode.
Babylon 5 and Star Trek: Deep Space NineEdit
J. Michael Straczynski began working on the Babylon 5 concept in 1986.  In 1987, he began pitching it, with a script for the pilot and conceptual artwork, to Hollywood executives.  He pitched the program (with pilot script, artwork, series bible, character descriptions, and synopses for approximately twenty-two episodes) to Paramount executives in 1989.  The series was greenlit by Warner Bros. in November 1991. 
Also in 1991, Brandon Tartikoff, then newly-appointed as chairman of Paramount Pictures, approached Rick Berman and asked him to develop a new Star Trek television series. Berman and Michael Piller discussed plans for the series with Gene Roddenberry prior to his death in October 1991. Star Trek: Deep Space Nine was officially greenlit in January 1992.  Filming on the Babylon 5 pilot, The Gathering, was completed before filming began on Deep Space Nine's pilot, "Emissary", but Babylon 5's post-production took longer, so "Emissary" aired on 3 January 1993 and The Gathering aired seven weeks later, on 22 February.
Straczynski has suggested that Paramount TV development executives may have "guided" the development of Deep Space Nine with the intention of co-opting Babylon 5.  He has, however, been careful to point out that he does not believe that Berman or Piller were aware of the Babylon 5 concept when they were developing Deep Space Nine, or that they deliberately ripped off Babylon 5.   If Straczynski had been right in his unspoken suspicions, then this had been a case of history repeating itself, but then with Star Trek on the receiving end; in April 1964 Gene Roddenberry and Oscar Katz presented the Star Trek is... pitch to television studio CBS, which was rejected by the studio, but not after been thoroughly questioned about it. It turned out that CBS had its own science fiction show, Lost in Space, under development at that time, and both Katz and Roddenberry in particular were convinced that CBS had picked their brains. (Star Trek Creator: The Authorized Biography of Gene Roddenberry) Like Deep Space Nine and Babylon 5, Star Trek: The Original Series and Lost in Space became science fiction franchise contenders in their day.
Despite his diplomatic stance however, Straczynski could not refrain from pointing out a number of similarities between Babylon 5 and Deep Space Nine, particularly their respective pilot episodes:
- set on space stations near space transit point – the Bajoran wormhole for DS9, a jumpgate for B5
- head of station has rank of commander – Benjamin Sisko, Jeffrey Sinclair
- female second-in-command – Kira Nerys, Laurel Takashima in "The Gathering", later replaced by Susan Ivanova
- second-in-command fending off attack on station at pilot's climax
- station contains a casino/bar and a central marketplace area for commercial activity – the Promenade, the Zócalo
- station visitors include diplomats, merchants, smugglers, and other travelers
- pilot episode features a character who changes shape or appearance – Odo, Minbari Assassin using a changeling net.
Straczynski also commented on what he perceived to be similarities in set and prosthetic designs, as well as the notion – mentioned in Deep Space Nine publicity but rarely acknowledged directly in the program itself – that the holosuites in Quark's would act as a virtual bordello.     In 1993, Straczynski noted a striking similarity between the just-aired Deep Space Nine episode "The Homecoming", in which Quark is branded on the head by the xenophobic and radical Circle, and the Babylon 5 episode "The War Prayer" (then in post-production), in which a Minbari is branded on the head by the xenophobic and radical Homeguard; he emphasized that no one on the Babylon 5 staff knew of the DS9 plot point until "The Homecoming" aired, by which point filming on "The War Prayer" had been completed. 
Later, in 1996, Straczynski said:
- "Sometimes it does bother me, and I wonder about what the heck's going on, when I see the only other space station series doing a big arc about alien forces infiltrating Earth government, and brewing civil war on Earth, at the *exact same moment* that we're doing it on our show; earlier, later, fine, but that they'd do basically the same thing at the same time feels like another attempt to co-opt what we're doing on this show. (Not copy; co-opt, which happens all the time. ....) If you kinda know the direction someone else is going, you try to jump ahead and get there first, so that the other either loses impact, or is considered simply an imitation. (Which is one reason why DS9 was hurried through post production to get it on the air a few weeks before B5's pilot, I suspect.)
- Are we being co-opted? I dunno. When I hear that there's a red-headed woman character on DS9 named Leeta (pronounced the same as Lyta); when I see them doing the same kind of arc we're doing but getting it out a little earlier, I will confess it does give me pause sometimes. I try to think the best under these conditions. For now, I'm asuming [sic] it's all just coincidence."
In the face of the rivalry, Majel Barrett-Roddenberry agreed to a guest appearance on Babylon 5 as a gesture of goodwill to encourage a reconciliation between the fandoms.   She played a widow of the late Centauri Emperor, whose greatness and vision for peace had not been fully appreciated within his own lifetime. She foresaw Ambassador Mollari's rise to power.
Aside from Straczynski's own observations, it should also be noted that Deep Space Nine too adopted a long, multi-season story arc from the third season onward in the form of events surrounding the Dominion War. The Star Trek franchise later repeated this to a lesser extent for the third season of Star Trek: Enterprise in the form of the Xindi threat story arc, and the Federation-Klingon War (2256-57) story arc, featured in the first season of Star Trek: Discovery.
Despite the signature importance of effects house Foundation Imagining had been for Babylon 5, the company was due to the above-mentioned unsavory studio politics let go from the production after its third season in 1995, leaving the company in dire straits. Yet, the services of the company were picked up the same year by the Star Trek franchise for their production Star Trek: Voyager, after its CGI vendor Amblin Imaging went defunct. However there were initial trepidations to do so, as Foundation's visual style was so associated with that of Babylon 5. (The Official Star Trek: Voyager Magazine issue 16, p. 35) In this regard David Livingston has observed, commenting on the use of computer-generated imagery in "Explorers", "We were reluctant to do computer graphics, but Peter Lauritson finally came around. He recognized how valuable it is. You can do more stuff with the ship, but you have to do it right. Not to pick on other shows, but Babylon 5 looks like computer-generated imagery. On Voyager and Deep Space Nine, you may not know some of these shots are not motion-control shots. They're really, really good if done properly. You have to spend a couple of extra bucks and get really good artists, but CGI just allows you to do more and you can build more elements into the shots". (Captains' Logs Supplemental - The Unauthorized Guide to the New Trek Voyages)
Additionally, Deep Space Nine Visual Effects Supervisor Gary Hutzel has stated, "My particular focus for our show, for Star Trek: Deep Space Nine, is that it should be a visual effects leader; we should never follow, we should never do what's been done before. CGI has certainly been used to various different degrees of success on Star Trek: Voyager, but I think it's still a hit-and-miss prospect, so I'm not interested in doing it." (Star Trek Monthly issue 31, p. 26) Still, Foundation has amply proven their mettle for Star Trek, even increasingly providing effects for Deep Space Nine's last two seasons as well, continuing to do so for the first season of Star Trek: Enterprise. Nonetheless, some Babylon 5 influences crept into the designs of some of the ships featured in Voyager; the designs of the Species 8472 bio-ship and Krenim weapon ship for example, echoed those of the Vorlon ships and the titular Babylon 5 station respectively, unsurprisingly perhaps, as these were (co-)designed by Steve Burg and Foundation CEO Ron Thornton respectively for either production.
After Foundation went bankrupt in 2002, its former Visual Effects Supervisor Adam Lebowitz has confirmed that all digital assets were left on the company servers when they were sold off at auction. It was this failure to maintain ownership by the respective studios that precludes any and all possibility for not only a remastered version of Babylon 5, as indicated above, but also such versions of Deep Space Nine, Voyager and Star Trek: The Motion Picture (The Director's Edition), which was the last project the company had worked on. 
Even though Babylon 5 has somewhat receded in the consciousness of science fiction fans, Star Trek's current owner, CBS Television Studios (or rather CBS Corporation), has not been able to refrain themselves of reminding television audiences of the fierce competition that existed at the time between the two franchise, or let the issue slide. In their hugely popular (and Star Trek friendly) sitcom series The Big Bang Theory, series regular Sheldon Cooper occasionally expresses his deep disdain for Babylon 5, while his roommate Leonard Hofstadter loves the series, yet losing each and every argument they have over the series. His most outspoken criticism was voiced in that series' third season episode "The Large Hadron Collision" (S03E15, 2010), where he stated that Babylon 5 "(...)failed as drama, science fiction and is hopelessly derivative", referring to the battle that raged at the time between that series and Deep Space Nine – and, as proxy for CBS, in the process implicitly accusing Babylon 5 of plagiarizing Deep Space Nine. In the later S05E21 "The Hawking Excitation" episode, it was also divulged that Sheldon had begged TNT up to three times to cancel Babylon 5. The stance taken in The Big Bang Theory has irked the still existing Babylon 5 fanbase, but has also enticed some science fiction fans, new to the series, to check out the series for themselves, because of Sheldon's aversion.  
As for the Babylon 5 creator himself, in a news notice in the German Star Trek magazine Trekworld in June 1999 it was mentioned that Paramount Pictures offered Straczynski a chance to work on the Star Trek franchise but he refused because he didn't want to work on someone else's series and was of the belief that trekkies had no love lost for him. Nonetheless, it has not prevented him to work on a treatment for "rebooting" the Star Trek franchise with Dark Skies creator Bryce Zabel in 2004, one that was turned down eventually, as the franchise by that time had decided to run with J.J. Abrams' alternate reality version, which ultimately resulted in the 2009 movie Star Trek. (X) 
Star Trek references in Babylon 5Edit
In the Babylon 5 episode "There All the Honor Lies" (written by Peter David), Commander Ivanova protests an attempt to sell "Babylon 5" merchandise on the station, saying, "We're not some Deep Space franchise – this place is about something!" David expected the line to be cut, but producer Straczynski insisted that it be kept, because it was "fall-down funny." David replied, "You people really ARE dangerous over there, aren't you?" 
In the episode "Voices of Authority", when an Earthgov political representative attempts to seduce Captain Sheridan, Ivanova quips, "Congratulations, captain... I believe you are about to go where everyone has gone before."
A blooper from the episode "Severed Dreams" has Bruce McGill's character, when asked where Robert Foxworth's character General Hague was, say "General Hague... is doing Deep Space Nine. It seems he was double-booked by his agent and nothing could be done." 
Actors who have appeared in Star Trek and Babylon 5Edit

- ↑ Robert Foxworth's characters on Babylon 5 and Deep Space Nine were very similar: both were high-ranking military officers who led coup attempts against civilian governments based on Earth (although the Babylon 5 coup was against a totalitarian regime). Both attempts failed. Foxworth had already been booked for a third appearance as General Hague on Babylon 5 when his agent accepted the Deep Space Nine role, which was filming at the same time. In response, J. Michael Straczynski killed off the character of General Hague off-screen (saying, "Never honk off the writer").   
- ↑ McGill was cast as a new character to replace the role of General Hague, played by Robert Foxworth, who had opted to appear in a two-part episode Deep Space Nine instead (see above).
