The Adventures of Buckaroo Banzai Across the 8th Dimension, often shortened to Buckaroo Banzai, is a 1984 American science fiction action/adventure film produced and directed by W. D. Richter and written by Earl Mac Rauch. The premise centers upon the efforts of the polymath Dr. Buckaroo Banzai, a physicist, neurosurgeon, test pilot and rock musician, 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 sci-fi film genres and also includes elements of comedy and romance.
After screenwriter W. D. Richter was introduced to novelist Earl Mac Rauch and hired him to develop a screenplay of Mac Rauch's new character Buckaroo Banzai, Richter teamed with producer Neil Canton to pitch the script to MGM/UA studio chief David Begelman, who took it to 20th Century Fox to make the movie. Box office figures were low and less than half of the film's production costs were recovered. Some critics were put off by the complicated plot, while others like Pauline Kael enjoyed the film, with Vincent Canby calling it "pure, nutty fun." Buckaroo Banzai has been adapted for books, comics, and a video game and has attracted a loyal cult following.
