angry birds

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.

The game will feature upgradable karts and characters with unique special powers in a fully rendered 3D world. Watch the trailer above.

Yes, it seems McDonalds in China is celebrating the Angry Birds' movie release with a bunch of food inspired off the movie, like the 'Naughty Green Pork Burger' above which includes a pork patty, egg, lettuce, mysterious jalapeno-esque sauce, and those iconic green buns.

China's also gearing up for the Angry Red Burgers, which naturally feature flaming red buns.

Hey, maybe it'll be a good game in disguise.

Defenders of the world!...and their eggs.
