And, well, others. On this Wednesday's Oprah, the Queen of all Media acknowledges another tuner besides her own The Color Purple by devoting the entire hour to the upcoming movie musical Hairspray, which hits theaters July 20. According to TheaterMania.com, in addition to interviewing the film's stars - John Travolta (presumably out of drag), Christopher Walken, Michelle Pfeiffer and Queen Latifah - the show will also preview at least one musical number. John Waters has officially made it. - Reporting by Raven Snook
