The ending *spoilers obviously*
Maybe this is completely obvious, but after Walter falls over and we see the cast and crew watching the movie, are we in a completely different story? Because the director talks about the scene with 'Steve' and 'the baby who plays Tristram'. Plus other things, like how 'Steve's girlfriend' was in the movie. I don't really see why, if this is indeed a third layer, adding another level was helpful/necessary. Anyway, any thoughts?
