Watch the Trailer for the 'Monsters, Inc.' Prequel 'Monsters University'

More than a decade ago, Pixar introduced us to the world of "Monsters, Inc." and taught us a few things about the value of laughter, both as a power source for monsters and as a source for a successful animated film. Now Pixar is giving us another "Monsters" movie, but despite it coming ten years later, it will actually be a prequel.

"Monsters University" is, as we reported earlier, the new Pixar offering giving us a look back at Mike and Sulley's college days. The movie will reunite most of the original voice cast, including Billy Crystal, John Goodman and Steve Buscemi. Here's the official synopsis:

"Mike Wazowski and James P. Sullivan are an inseparable pair, but that wasn’t always the case. From the moment these two mismatched monsters met they couldn’t stand each other. Monsters University unlocks the door to how Mike and Sulley overcame their differences and became the best of friends."

We see a little bit of that tension at work in the first teaser trailer for the movie, which features Sulley pulling a rather creative college prank on Mike.
