Saw the film on vimeo a decade ago I guess

There was woman in sort of a luxe looking coat (only) 

Took an elevator and was a dude pushing the buttons for her

Everyone in the film were kinda grim for some reason

Got off the elevator then was a nude female pianist

Also was a scene where a woman was in the bathtub with two dudes 

Edit) I didn't realize the boards were separate; sorry about that.
