Halloween has passed, but Paramount Pictures wants to give you a treat for putting on a creepy face. In promotion of its horror smash hit Smile 2, Paramount Pictures has set up a website where you can watch some of the film for free if you shoot the biggest smile into your computer’s camera.

To watch the preview, you have to first give Paramount access to your webcam and then smile the entire time it plays. Yep, you read that right; you have to grin at your computer for the entire seven minutes.
