After seeing this a couple of weeks ago, I can only remember a few, pretty physical things about the movie. There is a reference to Citizen Kane, so the original must have made quite a stir already when it came out. If they referenced any other movies, I didn't see them.
I do remember: Elisha Cook Jr as the frustrated 40s version of the screenwriter - looking like the shriveled version of Billy Wilder. There is some kind of count, posing as a poser of a count and counting. And there is a big swimming pool with all sorts of shenanigans going on - basically synchronicity swimmers on acid (something I would very much like to see).
