Has to be Clash of the Titans (the cheesey original, NOT the cheesey remake....dude, I mean, there's bad cheese and then there's Clash)
That movie is forever ingrained in my memory as the single greatest movie ever created, followed closely by The Dark Crystal and Watership Down.
RIP, dude...next time I see one of his skeletons fighting I'll name the one on the far left after him...exit, stage left, man.
