You know they’re mad, but do you know why? The Angry Birds Movie will focus on the question you never thought to ask as you played that infernal game on the pot every morning. The animation film, out mid-2016, has voiceovers by Jason Sudeikis, Maya Rudolph and Peter Dinklage. From the trailer, it sounds a little Kung Fu Panda-ish: misfit mocked by everyone later turns into saviour of universe, with help from bumbling friends. It may not be as revolutionary as the game once was, but it will be fun to see those green piggies go pop in 3D.
