TV Article 'Begin Again' trailer: Keira Knightley loves Adam Levine like a fool By Jeff Labrecque Jeff Labrecque Jeff Labrecque is a former senior editor at Entertainment Weekly. He left EW in 2018. EW's editorial guidelines Published on May 30, 2014 12:35PM EDT Begin Again, the summer musical romance from Once director John Carney, stars Keira Knightley and Mark Ruffalo as two wounded souls who connect in New York City. But the film also features two original coaches from The Voice, Adam Levine and Cee Lo Green. Levine, making his feature-film debut, actually plays a crucial role as Knightley's boyfriend, a good-looking hipster-folkie who gets blinded by fame and fortune when a few of his songs are used in the soundtrack of a popular movie. Green pops up as a version of himself; he helps Ruffalo's washed-up music exec in his last-ditch attempt to turn Knightley into a star. In the film's new trailer, Levine sings a more radio-friendly version of the tune his girlfriend wrote for him, "Lost Stars." Begin Again opens June 27.
