It is 25th anniversary The Adventures Of Buckaroo Banzai Across The Eighth Dimension. If you have not seen it, then you really should correct that. This is the sort of film that the term “cult classic” was created for. It is quirky and bizarre. There is some serious cheesiness in the dialog and story, but it is all self aware cheesiness. It all done for effect.
For the gamers out there this is the 1980’s version of Spirit of the Century. It is pulp action adventure characters placed in to a 1980’s context. Buckaroo Banzai is kind of a Doc Savage figure. He is great at everything. His crew are all equally interesting in their own right.
I could go on about this movie forever. I will include a trailer for it found on youtube. When you get a chance you should definitely track this down and watch it as a geek essential.
