Exclusive Media, Likely Story's Anthony Bregman and Judd Apatow are producing. The film, which is currently shooting, follows Gretta (Knightley), a popstar hopeful who relocates to the big city with her boyfriend (Levine). After she's dumped by the cad for the lure of fame and fortune, Gretta is discovered singing during an open mic night by a down-on-his-luck record producer (Ruffalo). The two realize they may be each other's last chance at achieving their dreams.
Green will play a successful hiphop star named Troublegum.
