Deadline:

Steven Spielberg’s next feature film is picking up steam, as he has found the next A-lister to join the ensemble of the film which is loosely based on the director’s childhood growing up in Arizona. Sources tell Deadline that Seth Rogen is set to play the favorite uncle of young Spielberg in the untitled pic from Amblin that already has Michelle Williams on board to play a role inspired by Spielberg’s mom, but with a separate and original voice.
