(written from a Production point of view)
Edward K. Milkis (16 July 1931 – 14 December 1996; age 65) was a Hollywood film and television producer hailing from Los Angeles, California. He began his career as post-production supervisor on Star Trek: The Original Series, before ultimately being promoted to associate producer in early 1968 for the show's third season. He went on to become a producer for Star Trek: The Next Generation during that show's first season.
Milkis was brought in to the original Star Trek in August 1966 by Gene Roddenberry - who had known him from The Lieutenant series on which he served as assistant editor -, after John D.F. Black left the series, and Robert Justman needed another hand to help him with the tasks of running the production. He was responsible for the special effects, and other post-production work.

Two decades later, Milkis was brought back to work on The Next Generation by Justman. However, by the time, Milkis was a producer on his own projects, and did not wish to work in a lower capacity for others, so his work on the series ended after a brief tenure in the first season.

Milkis has also served as an executive producer on such TV shows as Petrocelli (whose regulars included TOS guest actress Susan Howard and TNG guest actor David Huddleston) as well as the hit sitcoms Happy Days starring Don Most, Gavan O'Herlihy and Anson Williams, Laverne & Shirley starring David L. Lander and Michael McKean, and Bosom Buddies. Additionally, he was the producer for the films Silver Streak (1976), Foul Play (1978), and The Best Little Whorehouse in Texas (1982), and an executive producer on the 1994 comedy Exit to Eden (his final project). He passed away in Los Angeles at the age of 65.
In the original series second-season blooper real, William Shatner declares over the opening titles that the series is produced by Desilu, Inc. and was starring "Eddie Milkis."
