Yes, this video is clever, taking bits and pieces from Mr Bean and recutting it so it looks like the trailer for an upcoming movie in which Mr Bean is a terrifying Hannibal-type murderer. And yes, it is funny, and it has a great ending. And yes, it is somehow kind of creepy.
Even though it is worth watching, we think it's important to acknowledge that it is kind of easy to make Mr Bean seem like a weird maniac....because he is a weird maniac. But this makes him look like a murderous weird maniac, it's much different.
