Toy Story 2 was Pixar Animation Studios' first feature-length sequel.
Released in 1999, Toy Story 2 follows Woody after he is stolen by a toy collector and learns about a planned museum display. Pixar originally developed the project as a direct-to-video sequel, but expanded it into a theatrical feature after its story and production grew in ambition.
Cars 2 was Pixar's second sequel involving a different franchise, but it was not the studio's first sequel. Toy Story 2 established the pattern of Pixar returning to successful characters while building a story with major theatrical scope. Pixar later produced sequels such as Cars 2, Toy Story 3, Finding Dory, and Incredibles 2.
