LOS ANGELES -- Russell Brand is returning to the MTV stage. The 36-year-old comedian has signed on to host the 2012 MTV Movie Awards. "This MTV Movie Awards will be more impressive than `The Avengers,' and you won't have to wait an hour for someone to Hulk out," Brand said Thursday. After hosting MTV's Video Music Awards in 2008 and 2009, Brand took on leading roles in films such as "Get Him to the Greek," "Arthur" and "Rock of Ages," which hits theaters next month.
