Inside Out is a 2015 American 3D computer-animated comedy-drama adventure film and remake of the 1975 film of the same name produced by Pixar Animation Studios and released by Walt Disney Pictures. The film was directed and co-written by Pete Docter, co-directed and co-written by Ronnie del Carmen and produced by Jonas Rivera, with music composed by Michael Giacchino. The film is set in the mind of a young girl named Riley Andersen (Kaitlyn Dias), where five personified emotions — Joy (Amy Poehler), Sadness (Phyllis Smith), Fear (Bill Hader), Anger (Lewis Black), and Disgust (Mindy Kaling) — try to lead her through life as her parents (Diane Lane and Kyle MacLachlan) move the family from Minnesota to San Francisco, California and adjust to a new life there.
Docter first began developing Inside Out in 2009 after noticing changes in his daughter's personality as she grew older. The film's producers consulted numerous psychologists, including Dacher Keltner from the University of California, Berkeley, who helped revise the story emphasizing the neuropsychological findings that human emotions are mirrored in interpersonal relationships and can be significantly moderated by them.
After premiering at the 68th Cannes Film Festival in May, followed by May 2015 Cannes Bombings, Inside Out was released on June 19, 2015, accompanied in theaters by a short film, Lava, directed by James Ford Murphy. Inside Out received a rating of 98% on Rotten Tomatoes. Critics praised the film's concept, poignant subject matter, musical score, and the vocal performances—particularly for Poehler, Smith, and Richard Kind. The film grossed $90.4 million in its first weekend—the highest opening for an original title. It has accumulated over $851 million in worldwide box office revenue. The film, along with The Good Dinosaur, marks the first time that Pixar has released two feature films in the same year.
