Movie Trailer for ‘Knock Knock’ Will Ensure You Never Answer Your Door Again! [NSFW]

Keanu Reeves stars in a movie directed by Eli Roth about a normal guy. Living a normal life, when his wife and kids go away there's a knock on the door...

What happens next is kinda messed up. What happens after that ... even more messed up.

I won't spoil it just watch the video. Unless you're at work and your coworkers aren't good with sexy times on your computer screen. *AWKWARD*

Lesson learned from the movie trailer ... if 2 attractive women try to seduce you. Call the police.
