Inside Out 3 may be Pixar's most grown-up movie yet, considering a potential creative twist. Past films show Joy and Anxiety in control, but a new emotion should lead for fresh storylines.

The cast of Inside Out 2 includes Amy Poehler, Maya Hawke, Liza Lapira, Tony Hale, Phyllis Smith, etc. Let’s take a look at who voices Riley. Kensington Tallman is the voice of Riley in the film.

Inside Out 3 hasn't been announced, but if Pixar told Riley's story again, this fan theory makes a lot of sense.
