Has anyone seen the movie Spot?
It features David Arquette, the kid from 2½men and one of the mobsters from Goodfellas (I think).
I remember it very fondly as it was one of the first movies I ever bought myself.
It's about a police dog that somehow makes it to this lazy stoner and they go out on a big slapstick adventure, to top it all, the real owner of the dog is the big black guy from The Green Mile.
