It started in 1988, John Lasseter – co-founder of Pixar and former Walt Disney animator – and Pixar wrote, produced and directed a short film called Tin Toy.
This was the fourth Pixar film to be made using only computer animation and it won the 1988 Academy Award for Animated Short Film. In the 90s, Disney approached John Lasseter to create a sequel to Tin Toy, a Christmas special. Pixar, thinking 6 minutes wasn’t enough, asked Disney if they could make it 30 minutes. When President of Walt Disney Studios Peter Schneider heard about this, he suggested they make it full-length instead. Many of the employees at Pixar were surprised. And kids, that was the story how Toy Story was made.
