Alex Kurtzman (born 7 September 1973; age 44) is a producer and screenwriter who co-wrote the script for and executive produced the film Star Trek, along with writing partner Roberto Orci. Kurtzman and Orci later produced and (along with Damon Lindelof) wrote the screenplay for the sequel, Star Trek Into Darkness.  Kurtzman did not return to work on Star Trek Beyond. Kurtzman also consulted on the Star Trek video game.
Kurtzman and Orci previously were writers and co-executive producers on television's popular Hercules: The Legendary Journeys, which led to them becoming writers and co-executive producers for Xena: Warrior Princess. They also worked on Jack Of All Trades with Bruce Campbell. Kurtzman and Orci have been working with Star Trek producer and director J.J. Abrams for years, having written the 2006 Paramount Pictures film Mission: Impossible III and several episodes of Alias. They also wrote the screenplays for the 2005 film The Legend of Zorro (featuring Mary Crosby, with editing by Stuart Baird and music by James Horner) and the Michael Bay films The Island (2005, which featured Ethan Phillips, Glenn Morshower, and Randy Oglesby) and Transformers (2007, featuring Andy Milder, Glenn Morshower, W. Morgan Sheppard, Michael Shamus Wiles, and the voice of Robert Foxworth), and its sequel, Transformers: Revenge of the Fallen (2009, featuring the voice of Tony Todd and Robert Foxworth).
They did the final re-write of the screenplay for the film adaptation of the DC Comics graphic novel Watchmen, which stars Jeffrey Dean Morgan, Stephen McHattie, and Matt Frewer.   They also developed the science fiction/horror series Fringe with J.J. Abrams, which they executive produce with Abrams and Bryan Burk. 
Kurtzman and Orci are currently set to work on a film adaptation of Whitley Strieber's novel 2012: The War for Souls, which will reteam them with director Michael Bay. They are also the writers of the upcoming political thriller The 28th Amendment, which is set to star Tom Cruise and Denzel Washington. Orci and Kurtzman wrote the script for this movie in the late 1990s. They recently re-wrote the script, which is now in production at Warner Bros. Pictures.  
In addition to writing, Orci and Kurtzman currently produce films through their production company, Kurtzman/Orci (or K/O). Some of the films being produced by K/O include 2008's Eagle Eye and the 2009 romantic comedy The Proposal. They also produce the remake of Hawaii Five-O, which stars Daniel Dae Kim as Chin Ho Kelly, with guest appearances by William Sadler and Sidney Liufau.
In 2010, Kurtzman and Orci were nominated for a Saturn Award for Best Writing for Star Trek.  That year Transformers: Prime animated series, executive produced by Kurtzman and Orci, started airing on the Hub: the show features the vocal talents of Tania Gunadi, James Horan, Jeffrey Combs, Frank Welker, Tony Todd, Clancy Brown, Nolan North, and Dwayne Johnson.
In 2012, Kurtzman released his directorial debut, People Like Us, starring Chris Pine and Elizabeth Banks.
