Toy Story 3 is a 2010 American animated comedy-drama film produced by Pixar Animation Studios for Walt Disney Pictures. It is the third installment in the Toy Story series and the sequel to Toy Story 2 (1999). It was directed by Lee Unkrich, the editor of the first two films and the co-director of Toy Story 2, produced by Darla K. Anderson, and written by Michael Arndt, while Unkrich wrote the story along with John Lasseter and Andrew Stanton, respectively, director and co-writer of the first two films. The film's ensemble voice cast includes Tom Hanks, Tim Allen, Joan Cusack, Don Rickles, Wallace Shawn, John Ratzenberger, Estelle Harris, Jeff Pidgeon, Jodi Benson, John Morris, Laurie Metcalf and R. Lee Ermey, reprising their roles from previous films. Jim Varney, who voiced Slinky Dog in the first two films, died in 2000, 10 years before the release of the third film, so the role of Slinky was passed down to Blake Clark. The returning cast is joined by Ned Beatty, Michael Keaton, Whoopi Goldberg, Timothy Dalton, Kristen Schaal, Bonnie Hunt, and Jeff Garlin, who voice the new characters introduced in this film. In Toy Story 3, Andy Davis (Morris), now 17 years old, is going to college. Woody (Hanks), Buzz Lightyear (Allen), and the other toys are accidentally donated to Sunnyside Daycare, a daycare center, by Andy's mother (Metcalf), and the toys must decide where their loyalties lie.
