An international trailer has surfaced for Disney/Pixar‘s prequel Monsters University, which opens June 21. (This played before Wreck-It Ralph over the weekend in the UK; the domestic trailer is going out with Disney’s Oz The Great And Powerful when that pic premieres March 8.) The new full-length trailer fleshes out the plot that finds Mike (Billy Crystal) and Sully (John Goodman) in their college years — something the teaser released back in June with Brave accomplished pretty much spot-on in one scene. So what exactly will a full-length feature add to the party?
