Ashton Kutcher and Charlie Sheen have something to brag about during their big nights on television. Kutcher’s debut as Sheen’s replacement in the CBS sitcom “Two and a Half Men” was seen by 28.7 million people Monday. The Nielsen Co. said Tuesday that was more than any other episode in the show’s first eight seasons, when Sheen was the star. Meanwhile, Sheen appeared Monday as the “victim” of a Comedy Central roast that reached 6.4 million people. Sheen had been fired from “Two and a Half Men” last season for drug use and erratic behavior. He launched a weekslong tirade against his bosses, including show creator Chuck Lorre, and Lorre got revenge in Monday’s episode. Sheen’s Charlie Harper character was killed when he was hit by a subway train in Paris. Meanwhile, Kutcher appeared as an Internet billionaire unsuccessful in a suicide attempt over a crumbled relationship. He fell right into the show’s randy ways, picking up two women during a bar visit that same night. … Rap star 50 Cent has signed on to play a pimp in a movie detailing Alaska’s infamous serial killer, Robert Hansen. The Anchorage Daily News reports Curtis Jackson, the performer’s real name, has been cast for “Frozen Ground.” Academy Award-winning actor Nicolas Cage will star in the movie detailing the police investigation of Hansen, who preyed on prostitutes and strippers in the 1970s and early ‘80s in Anchorage. Hansen confessed to killing 17 women; some he let loose in the Alaska wilderness and hunted. Cage will play an Alaska state trooper who investigated the murders. John Cusack will play Hansen, and Vanessa Hudgens, of “High School Musical” fame, will play a victim who escaped. Filming is scheduled to start in Anchorage in October.
