Adam Levine may be trying to shed his "douchebag" label, but he plays a "lost," "redeemable" one alongside Keira Knightley in the musical film Begin Again, which marks his big-screen debut. The movie hit theaters today. The 35-year-old Maroon 5 singer and veteran coach of NBC's The Voice, who last showcased his acting skills on the show American Horror Story in 2012, sports a dark beard as Dave, a musician and ex-boyfriend of Knightley's character, Gretta.
