Elisabeth Moss, Rose Byrne and Sean Combs have signed on to join Get Him to the Greek, the Nicholas Stoller-helmed comedy for Universal Pictures.

Written by Stoller, the story centers on a record company intern (Hill) who has two days to drag an uncooperative rock legend (Brand) to Hollywood for a comeback concert. Moss will play the girlfriend of Hill's character, while Byrne will take on the role of Jackie Q, a scandal-plagued pop star and love interest of Brand's character. Combs will portray a record company executive.

Judd Apatow is producing alongside David Bushell and Stoller. Rodney Rothman and Phil Eisen are exec producing.
