A detailed description of each alternate ending & videos of some of them here: io9.
Films included are below (spoilers if you haven’t seen these, obviously). I’d seen some of these alternate endings already. Have to say they chose the right endings for these – especially The Thing & The Shining. Hate the sound of those alternate endings… And, OMG, the alternate ending of The Fly! Haha! Sorry, that looks SO dodgy.
