American screenwriter and producer Gene Roddenberry's work includes the creation of the Star Trek franchise. He began a writing career while he was a sergeant in the Los Angeles Police Department, and his first work to be bought by a network was The Secret Defense of 117, although it took four years to be broadcast. While writing for The Lieutenant, he began working on a science fiction premise that became Star Trek. He oversaw the production of the series for the first two seasons, but following budget cuts and the move to an unfavorable timeslot for the third season, he stepped back from working on Star Trek but remained credited as an executive producer. Star Trek was resurrected twice, first as an animated series, and then as Star Trek: The Motion Picture. The studio brought in a new producer for the sequel to the film, to which Roddenberry demanded creative control or else he would refuse an executive producer credit, instead only willing to be credited as creative consultant. This credit started with Star Trek II: The Wrath of Khan and continued through to Star Trek VI: The Undiscovered Country. (Full list...)
