Toy Story (1995) was the first feature-length film made entirely with computer-generated imagery.
Produced by Pixar Animation Studios and released by Walt Disney Pictures, the film follows Woody, a pull-string cowboy toy, and Buzz Lightyear, a space-themed action figure. Their rivalry changes when Buzz arrives in the bedroom of their owner, Andy.
John Lasseter directed Toy Story, which grew from Pixar’s earlier experiments in computer animation and its short film Tin Toy. The production established a new approach to animated feature filmmaking, using digital models, lighting, rendering, and camera movement rather than hand-drawn cels.
Toy Story is sometimes described simply as the first computer-animated film, but its more precise distinction is that it was the first feature-length film created entirely with CGI. Earlier films had used computer-generated sequences, and later Pixar releases expanded the technique with greater complexity.
