Joseph Kahn's Detention will see its theatrical release on April 13th. To give you a better idea of what this horror/comedy is all about, we have the new theatrical trailer and a photo gallery.

"Josh Hutcherson, Dane Cook, Shanley Caswell and Spencer Locke star in DETENTION, a hipster, teen horror-comedy where the local students of Grizzly Lake must survive their final year of high school. Standing in their way is Cinderhella, a slasher-movie killer who has seemingly come to life and is preying on the school’s student body. As the clock ticks and the bodies pile up, the likely suspects are embroiled in a race against time to stop Cinderhella and ultimately save the world… if only they can get out of detention."

Detention will open in a number of major cities, including New York, Los Angeles, Atlanta, Boston, Chicago, Houston, Miami, San Diego, San Francisco, and Seattle. For more information, visit: http://detentionmovie.com
