Disney Pixar recently released the first official trailer for the upcoming animated feature film, 'Inside Out'. The movie takes place partially inside the head of an 11-year-old girl named Riley, where her emotions have all been personified into characters.

In the film, the the different characters that will be portrayed include Joy, who will be brought to life by Amy Poehler, Anger played by Lewis Black, Disgust played by Mindy Kaling, Fear voiced by Bill Hader and Sadness, played by Phyllis Smith.

On that note, the main character of the movie, Riley, will be played by 'The Shifting' star Kaitlyn Dias.

Additionally, Riley's parents play a crucial role in the film, as noted by writer-director Pete Docter. The father of an 18-year-old son and a 16-year-old daughter provided some more insight about this in an interview with USA Today.

He said, "I started out doing a film about growing up, but it turned out it's a film about me watching my kids grow up,'' adding, "These parents are realizing that their kid is changing. That's difficult. But it is a part of life."

In terms of the film's plot, Riley's life has been changed drastically as her father has moved the family from the Midwest to work on a start-up company in San Francisco. At the same time, moviegoers will note that Riley's mother, who's upbeat and hip, is the emotional center of the family.

In regards to the parents, "These guys are the pillars on both sides," says Docter, "They are pivotal parts, knowing how joyful this kid Riley used to be and the young woman she's changing into."

Evidently, the show will focus on the animated emotions of each character, as they are all in it together, but possess different outlooks on the new changes in their lives.

Doctor says, "We're intercutting to show what's going on inside each of their heads behind the scenes," adding, "What seems like a simple family dinner is actually fraught with all sorts of emotional angst and drama."
