Thanks to the wondrous tool that is the internet, Vulture has just posted a delightfully twisted video that features the trailer for Mrs. Doubtfire re-cut as a horror film. Simply put, this might be one of the most brilliant things we have seen in a long while. It also proves that any footage of Robin Williams can be edited to make him look like a complete maniac. 

We've seen him play psychotic, middle-aged men before in One Hour Photo and Insomnia, but this might be the creepiest role of his career. The best part is that it wasn't even intended to be. Well enough of us blabbing on about how hilarious this is; just watch it for yourself.
