Fred Freiberger

Freiberger had been interviewed as a possible producer for Star Trek before it entered production in 1966, but had left the selection process due to a planned trip. In 1968, as a result of creative differences with broadcaster NBC, Star Trek creator Gene Roddenberry resigned as showrunner. Freiberger was again contacted and hired as producer for the series' third season. He assumed this role with a reduced budget that made the series more difficult to produce,[9] as well as a new "Friday night death slot" that resulted in a further decline in viewing ratings for what was already a low-rated program. Many Star Trek fans have since criticised Freiberger for being the cause of this decline, but actress Nichelle Nichols (who played Uhura) has written in his defense. Nichols argues that NBC's considerable budget cutbacks to the third season of Star Trek, in an environment of rising production costs and escalating actors' salaries, meant that:

you saw fewer outdoor location shots, for example. Top writers, top guest stars, top anything you needed was harder to come by. Thus, Star Trek's demise became a self-fulfilling prophecy. And I can assure you, that is exactly as it was meant to be ... In the third season [the] new producer Fred Freiberger did everything he could to shore up the show. I know that some fans hold him responsible for the show's decline, but that is not fair. Star Trek was in a disintegrating orbit before Fred came aboard. That we were able to do even what we did is a miracle and a credit to him. One day Fred and I had an exchange, and he snapped at me. Even then, though, I knew he wasn't angry with me but with his unenviable situation. He was a producer who had nothing to produce with.[10]

On 15 December 1975, Freiberger was confirmed as both script editor and producer for the second season of Gerry Anderson's British science-fiction TV series Space: 1999, recruited in part to make the series more appealing to the American market. To that end, Freiberger re-worked the series with major cast and character changes, a heightened emphasis on action and drama, and even ensured that signs appearing in the episodes used American English spelling.[6] He also wrote three episodes for the show's second season, under the penname "Charles Woodgrove", a pseudonym he had employed when writing for movies and television in the USA: he first used that name as a screenwriter on the movie The Beast from 20,000 Fathoms (1953), and subsequently in writing television episodes of the 1960s Western series Rawhide.

Freiberger has a dubious reputation in science-fiction fandom, due to his involvement in the final seasons of Star Trek, Space: 1999, and The Six Million Dollar Man, all cancelled on his watch (he also produced the cartoon series Josie and the Pussycats in Outer Space, which ran only one season, but most Saturday morning cartoons had short runs). In some circles this resulted in Freiberger being nicknamed "the Showkiller" or "the Serial Killer".[11] Both William Shatner and Nichelle Nichols of Star Trek refused to assign any blame to Freiberger in this manner.[12][13] From an interview by Canadian Kevin McCorry with Fred Freiberger in regard to Space 1999 not being picked up for a third season: "Because the powers in control decided that the first season was not successful does not mean that the productions were not well done in terms of the acting, the directing, the stories. There are many reasons why a series is canceled other than quality of the episodes. Ratings are the economic driving force. Are people watching the series? Obviously not enough. Lew Grade and his advisors decided that if the show was to succeed in the second year, it could not be the same as the first season. Changes were made. And obviously, the public did not respond so the series came to an end. It seems to me a waste of energy to argue that one year was better than the other - neither season attracted enough audience to sustain the series".[14]
