Before Mike (voiced by Billy Crystal) and Sully (John Goodman) became best workplace buds, they had to first pass monstrous muster at good ol' MU─that's Monsters University! In this charming animated prequel to "Monsters, Inc.," the frightful rivalry between the scare-studying student pair gets them booted from campus by their dean (Helen Mirren), making them realize they'll have to work together if they expect to make the horror roll.
