Toy Story is a 1995 American computer-animated family film, the first Disney/Pixar film to be made, as well as the first feature film in history to be made entirely with CGI. Directed by John Lasseter and featuring the voices of Tom Hanks and Tim Allen, the film was co-produced by Ralph Guggenheim and Bonnie Arnold and was distributed by Walt Disney Pictures. It was written by Lasseter, Joss Whedon, Andrew Stanton, Joel Cohen, and Alec Sokolow, and featured music by Randy Newman. Toy Story follows a group of toys who come to life whenever humans are not present, focusing on Woody, a pull-string cowboy doll (Hanks), and Buzz Lightyear, an astronaut action figure (Allen). The top-grossing film on its opening weekend, Toy Story went on to earn over $191 million in the United States and Canada during its initial theatrical release and took in more than $361 million worldwide. View-Master released a 3 reel set in 3D in 1995 prior to release of 3D films. The film was so successful it prompted a sequel released in 1999, Toy Story 2. Eleven years later, on June 18, 2010, an additional film, Toy Story 3, was also released. Both sequels were instant hits and garnered critical acclaim similar to the first.
