A - The Beast (1975 / France / Walerian Borowczyk)
Satire on church, society, and "morality" that doesn't leave anyone off the hook. 

Certainly true but who can forget the chase sequence with the giant continuously flowing phallus!

I've just rented Innocence by Lucile Hadzihalilovic, I definitely expect this to hit the spot for surreal and weird.

Madhuban brought up Cronenberg and Greenaway, I think the majority of their output would easily qualify for this thread.

Cheers Trev.
