Fake movie trailers

Recently on the Beating a dead horse thread, Darkage6 linked a video to an obviously fake trailer to Shrek 5 that, to my knowledge, was made as a "conceptual trailer" by the uploader to wonder what the movie's plot could be & honestly it's likely a better plot than what the actual movie's plot could end up being(though he eventually did say that it was a mistake & sent in a link to an actual confirmation for Shrek 5):

So I decided to look up some OTHER fake movie trailers & some of these are kinda wild, with some looking so fake that they become laughfests:






Wild stuff man
