Zombies may be really hot right now, but there's one thing that is (and probably always will be) a bigger deal: Pixar. Brad Pitt's 'World War Z' performed quite well in its opening weekend, but even the biggest zombie movie of all time couldn't keep pace with 'Monsters University.'
Two more films setting out to become summer blockbusters hit theaters this weekend, the first a sequel to a beloved animated tale and the other a zombie thriller adapted from a beloved novel.
