Monsters University Voice Cast Revealed - Here's Who John Ratzenberger's Playing!

As we march inexorably forward and Pixar's fourteenth feature film looms ever more, Entertainment Weekly have today got some exclusive details on who will be lending their voices to Monsters University - as well as some new posters and images from the film!

Joining the returning cast of John Goodman, Billy Cyrtsal and Steve Buscemi, - we already knew - are Oscar winner Helen Mirren, Dave Foley (A Bug's Life), Sean P. Hayes (Will & Grace), Charlie Day (Horrible Bosses), Pixar's Peter Sohn (director, Partly Cloudy; voice of Emile, Ratatouille), Joel Murray (Mad Men), Julia Sweeney (Stuart Little) and Alfred Molina (Spider-Man 2). Today, we learned that a lot of other exciting actors - including some Pixar favourites - are confirmed for the film.

Nathan Fillion voices Johnny Worthington, the central horned
monster.

Firefly's Nathan Fillion, The US Office's John Krasinski, and Bonnie Hunt (in her sixth Pixar film, after previously appearing in A Bug's Life, both Cars films and Toy Story 3, as well as a small role in the original Monsters, Inc.) have all been announced for the impressive voice cast. Fillion plays jock supremo Johnny Worthington, Krasinski voices a Monsters, Inc. scaring supervisor, and Hunt takes on the role of a young Mike's teacher.

Another Pixar favourite is unsurprisingly returning; the Emeryville studio's good luck charm, John Ratzenberger, is officially on board - although not reprising his role from Monsters, Inc. as The Abominable Snowman. Instead, Ratzenberger is cast in a slightly more generic role: "a Monsters, Inc. employee."

Also joining the Monsters U voice cast are Aubrey Plaza (Parks and Recreation), Tyler Labine (Tucker & Dale vs. Evil), Bobby Moynihan (Girls) and Beth Behrs (2 Broke Girls). To check out what roles those actors are filling, head on over to EW.com.
