Hardware Wars

''Hardware Wars'' is a 1978 American short science fiction parody film in the form of a teaser trailer for a fictitious science fiction film that parodies ''Star Wars''. The 13-minute film, which was released almost 18 months after ''Star Wars'', mainly consisted of inside jokes and visual puns that heavily depended upon audience familiarity with the original. The theme song is Richard Wagner's "Ride of the Valkyries". Provided by Wikipedia
