What actors and actresses appeared in Buckaroo Banzai Declassified - 2002?

There appears to be a misunderstanding. There's no movie or documentary titled "Buckaroo Banzai Declassified - 2002."

* Peter Weller as Buckaroo Banzai

* Ellen Barkin as Penny Priddy

* Jeff Goldblum as Dr. Emilio Lizardo/The World's Greatest Evil

* John Lithgow as Dr. John "Scotty" Scott

* Christopher Lloyd as New Jersey

* Clancy Brown as John Bigfoot

There's also a documentary titled "The Secret of the 8th Dimension: The Unauthorized History of Buckaroo Banzai" (2017) which explores the film's cultural impact.
