2PM's Junho and girl group After School made cameo appearances in the upcoming horror flick, 'White: Cursed Melody'. According to the sponsor, CJ E&M's movie department, Junho and After School are friends with the production team, and so as a favor to them, the idols made special appearances in the film. In the movie, Junho appears as an MC for an idol-only program, 'Challenge, Survival' , and for the music program, 'Music Fever.' It's been said that Junho did an excellent job acting as a popular star idolized by all girl groups. Meanwhile, After School will be performing their hit song 'Bang', but as the fictional girl group 'Pure'. As a popular group, they'll illuminate the hatred and jealousy between rival groups backstage.  'White: Cursed Melody' (starring T-ara Eunjung, May Doni, and Jin Sae Yeon) presents a different horror story with idols' cruel secret behind the stage. It will open in theaters on June 9th. Source & Image: Nate
