The Adventures of Buckaroo Banzai Across the 8th Dimension! (also more simply referred to as Buckaroo Banzai) is an American science fiction film that has reached cult film status. It was released in a 1984, directed and produced by W. D. Richter and concerns the efforts of the multi-talented Dr. Buckaroo Banzai (Peter Weller), a physicist, neurosurgeon, Samurai, rock musician, Jet Car driver and comic book hero, to save the world by defeating a band of inter-dimensional aliens called Red Lectroids from Planet 10. The film is a cross between the action/adventure and science-fiction movie genres, and also includes elements of comedy, satire, and romance. It is also made to feel like one in a series of movies, by the use of ongoing allusions to other characters, adventures and events.

Neurosurgeon/Rock Star/Superhero Buckaroo has perfected the oscillation overthruster, which allows him to travel through solid matter by using the eighth dimension. The Red Lectroids from Planet 10 are after this device for their own evil ends, and it's up to Buckaroo and his band and crime-fighting team The Hong Kong Cavaliers to stop them.
