Despite delivering their first original property in two years this week with the disappointing Brave, Pixar are going back to the well again next summer, with a prequel to their hit Monsters, Inc. Dan Scanlon is directing Monsters University, which sees Mike and Sulley back at college learning the ropes of the job we already know they excel at. The studio has debuted four slightly different teasers today, which give us little hint at the plot, only that pranks will occur. They don’t do much for me, but I sincerely hope this film breaks the Pixar slump. Check them out below, featuring voice acting from Billy Crystal, John Goodman, Steve Buscemi, Dave Foley, Julia Sweeney, Joel Murray and Peter Sohn.

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.

Monsters University arrives on June 21, 2013.
