1) Toy Story (1996)
Toy story movie was the brainchild of Pixar in collaboration with the owner, Steve Jobs. The partnership: the computer genius of Steve Jobs and the creative ingenuity of Pixar employees, especially John Lasseter, led to the creation of an innovative movie made entirely of CGI.
Casper, the movie that preceded Toy Story by six months, had the first ever CGI lead character, but toy story was the first ever feature-full length computer-animated movie after attempts were made on the movie, Tin Toy. This was a significant step as it would usher in a new decade of CGI blockbusters and animated films.
