Development on an Angry Birds movie has officially begun, but you'll have to wait until at least 2014 to see your favorite kamikaze birds on the big screen.

Rovio, the Finnish company that created the smash hit video game, has hired former Marvel Studios chairman David Maisel as a special adviser and executive producer for the upcoming film. The hire is the latest in a series of steps geared towards expanding the franchise into feature films. Just last month, Rovio acquired Finnish animation studio Kombo to begin work on short-form animated content based on the characters from the game.
