Oscar winners John Lasseter, the Chief Creative Officer of Walt Disney and Pixar Animation Studios, and Ed Catmull, the studios’ President, will take the stage in a live panel discussion celebrating “Toy Story,” which is the world’s first entirely computer-animated feature film.

The discussion will take place Thursday, October 1, at 7:30 p.m. at the Academy of Motion Picture Arts and Sciences’ Samuel Goldwyn Theater in Beverly Hills.

Twenty years after they collaborated on the film, Lasseter, the film’s director and co-writer, and Catmull, its executive producer and the creator of the digital animation program that made “Toy Story” possible, will share behind-the-scenes stories about the myriad challenges they faced as they imagined, invented and problem-solved their way into motion picture history.

Actor-director Jon Favreau will moderate the panel, which will feature additional guests to be announced.

Pixar Animation Studios, founded in 1986, was at the vanguard of the computer animation work that blurred the lines between art and technology. “Toy Story” was the company’s first feature film, after years of creating software, animated logos and television commercials with Lasseter and Catmull leading the way.

The film earned Oscar nominations for Original Song, Original Musical or Comedy Score, and Original Screenplay (the first for an animated film); Lasseter shared in the screenplay nomination as well as received a Special Achievement Award for his inspired leadership of the filmmaking team.

Catmull went on to receive an Oscar for his contributions to RenderMan, the software that was instrumental to the creation of “Toy Story” and the countless computer-animated films that followed.
