Rovio have announced that Jon Vitti, whose previous credits include The Simpsons and The Office, will pen the screenplay for their upcoming animated Angry Birds movie. Vitti, a Harvard graduate, won an Emmy for his work on King of the Hill, as well writing a couple of episodes of The US Office and being one of eleven credited writers for The Simpsons Movie. Worryingly though, he also co-wrote the Alvin and the Chipmunks film.
