In the 2013 film Monsters University, several scenes and character interactions were either fully improvised or significantly shaped by the actors' ad-libs. This was facilitated by director Dan Scanlon's decision to have key actors record their lines together in the same booth—a rarity in animation that allows for natural riffing and comedic timing.
The following are specific scenes and lines that were improvised or ad-libbed:
Director Dan Scanlon explicitly confirmed that the scene where the two-headed monster Terry and Terri Perry (voiced by Dave Foley and Sean Hayes) introduce themselves to Mike and Sulley was largely improvised.
The character Art, a New Age philosophy major, was intentionally designed to be an enigma. Charlie Day was given significant freedom to experiment with the character’s "inner weirdness."
In the recording sessions for Chet, the obnoxious vice president of the Roar Omega Roar (ROR) fraternity, Bobby Moynihan worked with the director to find the most "hateable" persona.
Billy Crystal and John Goodman famously insisted on recording their lines in the same room to recapture the chemistry from the first film.
Though not in the final theatrical cut, there is a prominent deleted scene titled "Drama Class" where Mike and Sulley are forced to participate in an actual improv exercise. In this sequence, they are told to pretend to be a flower (Mike) and a bunny (Sulley). While the scene itself was scripted to depict improv, the actors' performances within it were highly improvisational in nature to match the awkwardness of the situation.
The summary mentions the scene but misses the context that it was deleted because it resolved the conflict between Mike and Sulley too early or in a way that didn't fit the final story arc.
The summary focuses on comedic improv but misses that Crystal and Goodman also recorded emotional scenes together (like the lake scene) to capture authentic dramatic chemistry, not just jokes.
In Monsters University (2013), improvisation played a significant role, primarily due to the decision to have Billy Crystal (Mike) and John Goodman (Sulley) record their lines together in the same studio—a rarity in animation that allowed them to riff and overlap dialogue naturally. Notable improvised moments include the "Dance Major" backstory for the two-headed monster Terry and Terri, which was ad-libbed by Sean Hayes. The character of Art (Charlie Day) was also heavily shaped by improvisation, as the character was initially undefined in the script until Day's performance gave him his specific weirdness. Additionally, a deleted scene titled "Drama Class" features Mike and Sulley performing an improv exercise (as a flower and a bunny), where the actors themselves improvised the intentionally bad dialogue.
