Keira Knightley and Maroon 5 frontman Adam Levine are making some sweet music together in the upcoming music-infused romance "Begin Again" from "Once" director John Carney

The latest trailer for the film provides lots of hugging, high-fives, slow-motion and, of course, inspirational music, including the new Levine tune "Lost Stars."

With echoes of "Once," Knightley and Levine play two romantically involved musicians who go their separate ways after Levine makes it to the big time. Knightley then teams with a down-and-out producer, played by Mark Ruffalo, to jumpstart her career. Levine's "The Voice" collaborator Cee Lo Green also pops up, playing a spin on his own persona. 

The wide-ranging cast also includes Hailee Steinfeld and Catherine Keener.

"Begin Again" opens June 27.
