We've been huge fans of Rock of Ages since it first exploded on to Broadway in 2009. So you only imagine how thrilled we were when we learned the smash musical would be hitting the big screen. With Julianne Hough, Diego Boneta, Tom Cruise and tons of other Hollywood big shots in the lead roles—not to mention choreography by Mia Michaels!—the show is bound to get you on your feet and dancin' like a fool. Don't believe us? Watch the cast rocking out last night on "Dancing with the Stars."
