The origins of Alien are generally cited as this 1974 film which started as a USC student production by John Carpenter with help from Dan O'Bannon, and then grew out of control into a feature film. In this film, O'Bannon used an inflatable ball for an alien, but it got him wishing he could make a film with a much better creature down the road. Name this sci-fi comedy film with the tagline, named for a scout ship which serves as the film's setting.
