Plenty of famous actors have adopted lead roles in Pixar movies over the years, but the studio has also provided some since-forgotten supporting roles for Hollywood stars in its most popular projects. Recognizing all these actors can be difficult since it’s only their voices that are included in the movies, but several of their characters have become fan favorites without audiences actually realizing exactly who plays them. These cameos and supporting roles can be a really fun way for actors to get involved in Pixar movies and play characters that they’d never otherwise get a chance to.
