Doubt Trailer Is Full of Sunshine and Smiles - Doubtful

We have a vague recollection of a forgettable and slightly depressing film starring loads of Oscar winners and based on a Pulitzer Prize winning play. It was called Proof. So here is a hopefully not forgettable film which will be hella depressing starring loads of Oscar winners based on a Pulitzer Prize winning play. It's called Doubt. Amazingly, it's not a sequel. Even more amazingly, I didn't blow my brains out after watching the trailer.
