With Brave releasing this week, it’s easy to forget that Pixar has another big movie on the horizon. Monsters University tells the story of how Mike and Sully met at the University of Fear, before 2001′s Monsters, Inc. The movie is Pixar’s first prequel and features Billy Crystal and John Goodman as the returning voices of these lovable monsters. The cast will also include some new voices, including Dave Foley, Julia Sweeney, and Rob Riggle, when the film releases on June 21, 2013.
