The movie takes us to an island populated entirely by happy, flightless birds – or almost entirely. In this paradise, Red (Jason Sudeikis, We're the Millers, Horrible Bosses), a bird with a temper problem, speedy Chuck (Josh Gad in his first animated role since Frozen), and the volatile Bomb (Danny McBride, This is the End, Eastbound and Down) have always been outsiders.
