The Alamo Drafthouse Cinema has announced plans for a special screening of the first installment of director Andres Muschietti's two-part adaptation of Stephen King's It on Saturday, Sept. 7, a day before the film's official premiere. There is one slight catch: All attendees are expected to dress as clowns.

The cinema is renowned for its strict adherence to cinema etiquette, so don't expect a T-shirt with the Joker on it to get you through the door.

The notice on the Drafthouse's website offers clear guidance for all those thinking about buying tickets: "For this special screening of It, all attendees should arrive dressed as a clown in order to attend. Please arrive early and join us in the Barrel O' Fun beginning at 5:30 p.m. for an It pre-party, where we will have face-painters available for clown 'touch-ups,' a photo booth, raffles for prizes and other terrifying merriment. Please arrive in your own Pennywise best and be ready to float with us."

Coulrophobes, and anyone else who just doesn't like clowns, should probably stay away, but this could be the perfect event for both Juggalos and dedicated cosplayers alike.
