According to Comicbook.com, a new film about Supergirl is planned to go into production. Reports have surfaced claiming that the movie is going to take place in the 1970s and center on a version of Super Girl who made it to Earth before Super Man. Producers hope that by setting the film in a retro time period period will help to distinguish its content from that of the Supergirl TV series which is about to enter its fourth season on The CW.
