Disney has released new images from Monsters University. Like we saw in previous images and trailer, these new images show that Mike Wazowski (Billy Crystal) was a nerd, and Sulley (John Goodman) was his frat boy tormentor. Monsters University is the story of how they went from enemies to besties. ““They both approach life in different ways,” producer Kori Rae tells EW. “Mike is the go-getter type, anything is possible, and he’s the super-hard worker. Sulley is different because he’s a great scarer, he has this natural ability, but Mike has to work for it.”

Hit the jump to check out the new images. The film also features the voices of Steve Buscemi, Dave Foley, Julia Sweeney, Joel Murray, and Peter Sohn. Monsters University opens June 21, 2013.
