These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
YMMV: The Adventures of Buckaroo Banzai Across the 8th Dimension
Ear Worm: The theme that plays over the end credits.
Genius Bonus: When he first meets Reno and Perfect Tommy, Jersey mistakes each of them for Pecos. Later comics reveal that Pecos is a woman.
Ham and Cheese: Everyone in this film seems to be having the time of their lives, but especially John Lithgow. The fact that everyone went so far over the top is probably why it has retained the cult status it has instead of being entirely forgettable.
In fact, in an attempt to actually produce the announced sequel, Buckaroo Banzai vs. the World Crime League; all of the former cast were reported as being enthusiastic about returning to their roles. Unfortunately, the film remained stuck in Development Hell.
"I'm sure in the miserable annals of the earth you will be duly enshrined!"
Retroactive Recognition: During the opening credits (When William Traylor and Carl Lumby's credits are on the screen), there is a square yellow box equipment-thing in the background, with what look like two white eyes and brown for the lower third. It really looks like SpongeBob SquarePants, though could never have been intended to. This wouldn't even be worth mentioning save for the fact that Clancy Brown (Mr. Krabs) plays Rawhide.
Buckaroo's suit during the end credits looks a lot like Peewee Herman's outfit. Although Paul Reubens was already something of a cult figure as Peewee Herman, it wouldn't be till the next year with Pee-wee's Big Adventure that the character would catapult to national consciousness.
