Pixar hasn't made an instant classic since 2010's Toy Story 3, but this summer's Inside Out is probably going to change that. Not only is the concept genius—the main characters are the different emotions inside a little girl's head—but the new trailer just came out and it looks fantastic. The story takes place largely inside the mind of the 11-year-old Riley, where her feelings—Joy, Fear, Disgust, Anger, and Sadness—navigate the day-to-day ups and downs of being a human being. But the story really picks up when Joy, voiced by Amy Poehler, has to travel to the far recesses of Riley's mind to set things right after her father moves the family to San Francisco and emotional turmoil ensues.
The movie looks filled with the wit we've come to expect from the folks at Pixar (Brain freeze!) not to mention the heart. Mindy Kaling, Lewis Black, Bill Hader, and Phyllis Smith voice the other emotions. Inside Out hits theaters on July 19, and it's Bring Your Own Kleenex.
