I don't see why the mask talking wouldn't work in the film. It's clearly there to demonstrate just how insane and crazy Decker is. It's a shame it's not in the DC. It could just be my mind wanting to think there was more to that cell scene. I seem to recall more touching and grabbing. Obviously the book had a hardcore sex scene there but I recall being happy and surprised to see some raunchiness there in the Cabal cut. I'll have to pop in the bonus disc soon and see what footage they've included there.
