If you've ever played the mobile video game Angry Birds, you might have found yourself wondering -- why am I sling-shotting cartoon birds at grinning green pigs? Why are these birds so angry? What have the pigs done to deserve this destruction? "Angry Birds," the movie, is here to fill in that backstory, to answer the questions that may or may not have been asked, and provide motivation for the avian rage. The film, directed by Clay Kittis and Fergal Reilly, from a screenplay by "Simpsons" writer Jon Vitti, proves to be more than just a gimmick, and doesn't skimp on any of the quirky wackiness that you might expect from a film about blob-shaped, flightless birds battling pigs.
