Pixar prequel is scheduled to open June, 2013
Following last year's Brave, Pixar is going back to familiar faces for June 2013's Monsters University, with a look at the school days of the returning John Goodman, Billy Crystal, and Steve Buscemi as Sully, Mike, and Randall. For the Japanese version, we get Hidehiko Ishizuka, Yūji Tanaka and Yutaka Aoyama, new footage and some subtle changes to the animation (look at the slug guy's teeth).
Also of note in the Japanese dub, Fumihiko Tachiki (Evangelion's Gendo, Gintama's Madao) is The Abominable Snowman.
