Gene Roddenberry's Secret Agent Saves Earth, Forty Years Later

Do you remember the Star Trek episode which had the Enterprise travel back in time to the Earth of the 60s. Kirk and crew discover that a mysterious person seems bent on sabotaging a certain rocket launch. The episode was a little on the strange side even for Trek. It seems the mystery man is in fact a time traveling alien and his cat his shape shifting partner. Their efforts are aimed at protecting earth by delaying the rockets launch. The strange back story to this episode is the fact that this show was supposed to be a "trailer" of sorts for a program that Gene Roddenbery wanted to produce. As intriguing as the concept was, nothing was ever to come of the idea. (sigh) This year, however, all that will change with the first issue of Assignment: Earth, a series based on Roddenberry's concept for the unmade TV show. Written and drawn by long-time Trek fan Byrne. The five part series, which advances the story one year with each new issue, launches in May.
