The Dirt Devil 'The Exorcist' is the greatest commercial I have seen in some time. The ad is a spot-on spoof of The Exorcist with a hilarious twist.
I'm not going to ruin what happens, but let's just say that the young woman in this video is possessed by a different kind of devil. The commercial was produced by German film school Filmakademie Baden-Württemberg and has top-notch lighting and acting, which isn't something you can say about most commercials.
The ad manages to spoof one of the scariest movies of all time and get its brand message across. If that isn't an advertising win, I don't know what is. You can check out the video, along with other outrageous and original commercials here.
