Star Trek: Phase II was devised in 1977 to be a sequel to the original Star Trek – the TV series featuring William Shatner as Captain Kirk, Leonard Nimoy playing Spock, and so on. Although the series was canned, some of the design themes were adopted by the 1979 movie, Star Trek: The Motion Picture (including the redesigned Starship Enterprise art used in the movie poster, above), and storylines in the 1987 television series, Star Trek: The Next Generation

As Star Trek: Phase II reached a fairly late stage in production before its cancellation, there is some awesome concept and production art for the sequel that never was, all created by Mike Minor. Trekkies and concept artists alike are sure to enjoy the images below – scroll through them to get a glimpse of what you missed on the small screen.
