Original post here. Image is a movie poster containing the text “The sky is the limit! Star Babe: A sexual space fantasy. Staring Tomi La Roux as Star Babe and Jason Welles as Captain Marvellous. Featuring Wendy Long as Twinkletoes and Cinthia Lee Scott as Milky Way. Plus a total galaxy of heavenly bodies in twisting eastman color. An Evolution Enterprises release.” This image was researched by Bacchus at ErosBlog as part of the “Γ commission.” It was originally published at Hedonix as “Γ 014 – Star Babe.” Here is Bacchus’s research:

This is, as it appears to be, a movie poster for the 1977 Star Babe (“A sexual space fantasy” according to the poster.) The IMDB listing offers only a one-line plot summary: “The Star Angels are sent to the planet Phallus to prevent a takeover of Earth.” The Women In Prison Films website makes it clear (if there was any doubt) that Star Babe is a hard-core porn sci-fi movie; five explicit screenshots are provided.

A blog post here asserts that Star Babes was a porn parody of Star Wars. The post displays attractive posters from several other porn parodies of sci-fi films, including Sex World (parodying West World), Sensual Encounters of Every Kind (Close Encounters of The 3rd Kind), and Souperman (guess!).
