The world may finally figure out why those birds are just so angry all the time.
A teaser trailer for The Angry Birds Movie was released today, and a star-studded cast will voice the birds and pigs you've come to know on the front of your smartphone screen.
The cast includes: Jason Sudeikis, Josh Gad, Danny McBride, Maya Rudolph, Kate McKinnon, Tony Hale, Keegan-Michael Key, Bill Hader and Peter Dinklage.
Let's hope they hit this one out of the park.
The Angry Birds Movie will come to theaters May 2016.
