The opening scene of recently released horror film Smile 2 is now available to watch online for free – but there’s a suitable twist if you want to press play.

The first seven minutes of the sequel are now streaming on the film’s official website, Bloody disgusting reports, but the clip will only play if you smile. Visitors to the site are asked to turn on their webcam, and the video stops playing if you stop smiling — which is a lot of cheese.
