Last week a co-worker loaned me a copy of The Adventures of Buckaroo Banzai Across the 8th Dimension, and I watched it yesterday.
If you're in the mood for a great 80s flashback movie, this is it. Buckaroo Banzai has it all: before-they-were-famous actors and crew; a group of gun-toting, hard-rocking scientists; a heroine named Penny Priddy; a wondrous technological marvel that looks vaguely like a flux capacitor; a jet-powered Ford that looks vaguely like the Space Shuttle; a choreographed musical scene at the end; serious use of the phrase "wherever you go, there you are."
Great fun if you can track it down.
