Horror Hunks: Playback (2012)

The horror thriller Playback centers on the investigation into a missing teen, which seems to have a connection to a family's murder tragedy from years before. Add in some gory murders and strange video tape footage and it's not long before the film's teen characters begin to meet their grizzly ends. The birthday of one of the leads, Brianna, brings out her partying classmates. Three of those young men present their gift during the party, which consists of them mooning her to show off their happy birthday sign. The three naked extras are sadly uncredited. The film's trio of hot male leads Johnny Pacar, Jonathan Keltz and Toby Hemingway all stay clothed unfortunately.
