On Tuesday evening, Hollywood High School opened its doors for the premiere of Warner Bros.' new found-footage horror flick, The Gallows.

The film stars a plethora of young Hollywood, including Reese Mishler, Pfeifer Brown, Ryan Shoos and Cassidy Gifford, under the direction of Chris Lofing and Travis Cluff, who also wrote the screenplay. All were on hand for the LA premiere, with some help from some famous friends and parents.

See photos from the event below and, if you haven't already, watch Cluff and Lofing discuss how they turned a $250 trailer into a feature film. The Gallows hits theaters tomorrow, July 10.
