Pixar Unleashes First Full-length Trailer For 'Monsters University'

We've seen quite a few teasers scared up already for Pixar's latest animated adventure, "Monsters University," but now the long overdue follow-up to their 2001 hit "Monsters, Inc." has finally matriculated into the world of full-length trailers.

Rather than simply picking up on what James P. Sullivan, "Sulley" (John Goodman), and one-eyed Mike Wazowski (Billy Crystal) have been up to in the business of playful boo tactics over in Monstropolis lately, the film journeys way back in time to show how the pair came to be that lovably inseparable duo the world knows. As it turns out, back in college, the then-potluck roomies weren't exactly best pals right out of the spooky gate and had quite a competitive spirit going over which of them could be the best student of scaring. Sulley, obviously, has the edge on size.

The first trailer comes by way of the United Kingdom. Steve Buscemi, Jennifer Tilly, Kelsey Grammer, Frank Oz, Ken Jeong, John Ratzenberger and J.B. Smoove also voice, while Dan Scanlon of "Cars" directs as former "Inc." helmer Pete Doctor jumps from "Brave" on to "Inside Out" for the studio.

"Monsters University" hits theaters on June 21, 2013.
