Oh man... sorry, my post won't be of help, but I do remember going to a site just a few months ago that had this very thing.
It had all endings from pretty much every console and game in existence (well, all the pretty popular games, anyway).
I can't remember for the life of me what the URL was... but it wasn't actual movies, it was screen shots along with text of what happens.
[edit]
Sweet, I had it bookmarked, but unfortunately there's no PS2 endings...
