It's not easy being a tween.

In Disney•Pixar's Inside Out, five emotions are based in headquarters, the control center inside 11-year-old Riley Anderson's mind. Joy (Amy Poehler) finds the fun, Fear (Bill Hader) heads up safety, Anger (Lewis Black) ensures all is fair and Disgust (Mindy Kaling) prevents Riley from getting poisoned, physically or socially. Sadness (Phyllis Smith) isn't too sure what her role is—and frankly, no one does.

For most of her young life, Joy has been Riley's guiding emotion. But after her parents (voiced by Diane Lane and Kyle MacLachlan) move the family from Minnesota to San Francisco, Sadness overcomes her.

Director Pete Docter co-wrote the screenplay with Josh Cooley and Meg LeFauve. Michael Giacchino, who also scored The Incredibles, Ratatouille, Up and Cars 2 for Disney•Pixar, composed the film's music.

Inside Out is in theaters Friday. The 94-minute movie is rated PG.

Here's what critics think of Disney•Pixar's latest movie:

• "Pixar's 15th feature is another landmark, an unmissable film triumph that raises the bar on what animation can do and proves that live action doesn't have dibs on cinematic art. Oh, did I say it was funny? It is, uproariously so, when you're not brushing away a tear," Rolling Stone's Peter Travers writes.
