Begin Again's a first for its stars
Keira Knightley and Adam Levine's movie Begin Again has turned out to be an experience of firsts.
Actress Knightley sings in the film and Levine, frontman of the band Maroon 5, acts.
Speaking on the red carpet in New York where the film closed the Tribeca Film Festival, Knightley recalled being "completely terrified" to sing.
And Levine, who said he was "blown away" to be walking a red carpet for a film role, said he enjoyed the experience so much he might have caught the acting bug.
Begin Again is directed by John Carney, who was behind the successful musical drama Once. It also stars Mark Ruffalo, Hailee Steinfeld and Catherine Keener. CeeLo Green also has a small role.
The film opens in the US in July.
