Pixar’s Monsters University is a bit of a class reunion for our favorite creatures of the one-eyed and furry variety. In the prequel, Billy Crystal, John Goodman, and Steve Buscemi will reprise their voice roles from 2001′s Monsters, Inc., but the new film will also feature plenty of new characters.

EW can exclusively reveal more actors who are bringing life to the animated movie’s monsters. Among the talent lending their voices to the film are Nathan Fillion (Castle), John Krasinski (The Office), and Bonnie Hunt (Cheaper By the Dozen).

Hunt’s acceptance into Monsters University marks a return to the Pixar family. She also voiced characters in A Bug’s Life, Cars, Toy Story 3, multiple short films, and even Monsters, Inc., though as a different character than her role in the prequel.

Previously announced voice actors include Sean P. Hayes (Will & Grace), Charlie Day (Horrible Bosses), Aubrey Plaza (Parks and Recreation), Alfred Molina (Spider-Man 2), and Helen Mirren (The Queen).
