(Spoilers!) Let me get this right:
So the Devil sends Don Juan back to earth just so he can pop Bibi Andersson's cherry, you know, because that's the kind of goofy s--t the Devil did back in the 60's when he was bored.
Also, Don Juan's wingman (who totally looks like Tom Waits and Dean Stockwell's love-child) screws a minister's wife.
I know they all can't be "Persona" or "Face to Face," but this one was just plain silly.
