"You start dancing, I'll blow your brains out."
I can singlehandedly quote this movie forwards, backwards, diagonally, & any other way I can think of. I know it like the back of my hand. One of my go-to comfort movies. Along with The Mummy.
Also, the "Cuban Pete" & "Hey Pachuco!" sequences live in my head rent-free 24/7/365.
