First Teaser For the 'Angry Birds' Movie

All you Angry Birds obsessives, here's your first look at the much anticipated (?) movie coming out next May. It basically looks like your typical animated kids stuff with all the required comedians in the world lending their voice acting ability- I have a question. Do the names on the credits actually help sell these movies to anyone? Whatever happened to specific voice actor talent that used to be hired to do voices for animated features? I just seriously doubt that people like Bill Hader and Jason Sudeikis lend box office might to a movie about angry birds.
