It turns out that the Charlie, Charlie Challenge, the current ersatz Ouija board craze among teenagers which was condemned by a Philadelphia priest who warned of its evil dangers is just another viral marketing campaign for a movie. So you can relax. Evil Mexican demon Charlie is not going to come and get you. The game is part of the marketing for new horror film The Gallows.
The official synopsis of the movie is “20 years after a horrific accident during a small town school play, students at the school resurrect the failed show in a misguided attempt to honor the anniversary of the tragedy – but soon discover that some things are better left alone.” Yes, some things are better left alone: stupid social media crazes, for instance.
