'The Angry Birds Movie's' Hatchlings Deliver Holiday Cheer in New Promo

Just so you don't think "The Angry Birds Movie" is all about invading Bad Piggies and, well, angry birds, the Hatchlings of the CG-animated film have popped up to deliver season's greetings in the most adorable way possible: with a fumbling Christmas carol.

Directed by Clay Kaytis and Fergal Reilly, "The Angry Birds Movie" stars Jason Sudeikis as the easily ruffled Red, who must team with his equally prickly friends Chuck (Josh Gad) and Bomb (Danny McBride) to fight back against the Bad Piggies (Bill Hader, among them) when they encroach upon their all-bird paradise.

Opening May 20, the film also features Maya Rudolph, Hannibal Buress, Kate McKinnon, Keegan-Michael Key, Tony Hale and Peter Dinklage.
