Buck Rogers (1979); the theatrical release of the pilot "Awakening." Decent "Star Wars-on-a-budget" movie. Entertaining, though pretty silly at times and the robot Twiki is truly obnoxious ('70s JarJar). But it had Erin Gray, and thus cemented my adolescent crush on her... haha.
This is a movie poster for Clash of the Titans made in 1981. This movie follows the story of Perseus and the slaying of Medusa. This story told by Ovid in 8 AD has stuck around and is still being told today.
