12. 'Rock Star'
Based loosely on the true-life story of Tim "Ripper" Owens, a Judas Priest cover band singer who got hired to be frontman for the real Judas Priest, this metal-fueled movie starts off as comic fantasy, then becomes something more dramatic. Playing Chris Cole, a variation on Owens who gets hired to sing for fictional rock gods Steel Dragon, Wahlberg gets to put his pop-star boldness and magnetism to good use, sprinting and bounding all over the stage; that he also gets to play the type of working-class underdog he loves so much is a bonus. The film is too all over the place tonally to work, but man, the star is aces.
