Scooter Lindley: Dad! Dad! Buckaroo's in trouble! Casper Lindley: Say what?
Buckaroo Banzai: You can check your anatomy all you want, and even though there may be normal variation, when it comes right down to it, this far inside the head it all looks the same. No, no, no, don't tug on that. You never know what it might be attached to.
[intro to a flashback] Television voice: Nineteen thirty-eight! Can you imagine what it must have been like then... then... then...
Lord John Whorfin: May I pass along my congratulations for your great interdimensional breakthrough. I am sure, in the miserable annals of the Earth, you will be duly enshrined.
Rawhide: Dr. Banzai is using a laser to vaporize a pineal tumor without damaging the parthogenital plate. A subcutaneous microphone will allow the patient to transmit verbal instructions to his own brain. Observer: Like, "raise my left arm"? Rawhide: Or "throw the harpoon." People are gonna come from all over. This boy's an Eskimo.
Peter Weller is really playing the guitar in the nightclub scene.
Many names and terms were taken from Thomas Pynchon's book "The Crying of Lot 49".
W.D. Richter wrote a screenplay for a sequel to this film. The never produced "Buckaroo Banzai Against the World Crime League" was eventually re-tooled into Big Trouble in Little China.
Overall concept and several names appear to be taken from the Doc Savage pulp magazines of the 30's and 40's: both main characters are multi-talented surgeons, adventurers, and musicians; and both have an inner circle of sidekicks with nicknames (Renny, Ham, Monk, Long Tom, and Johnny, compared to Reno, New Jersey, Perfect Tommy, and Rawhide).
Jamie Lee Curtis played Buckaroo's mother in a flashback, but this scene was cut.
