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. (Watch the trailer.)
In an interview with E! News, the 29-year-old British actress, sitting beside Levine, offered her co-star encouraging words about his performance.
"It was actually one of the most difficult things to sort of calibrate in the film, was how douchey that character should be...It was actually the trickiest thing, I think," Knightley said, smiling at him. "So it's, again, very impressive. For your first film, it was a very tricky one to balance."
