Monsters Inc
The best movie mashups involve two films with completely different tones - like "Fifty Shades of Frozen" or a Michael Bay version of "Up" - so that's why this new take on "Monsters, Inc." is so awesome.

YouTube user Ross Thompson of The Unusual Suspect created a trailer for the Pixar movie in the style of Ridley Scott's "Prometheus." It recasts the cuddly, feel-good film as a dark, ominous horror movie, with quick Scott-like cuts building mystery and tension.

Collecting screams, indeed.
