What is the name of the first Pixar film to feature Michael Giacchino as composer?

The Incredibles was the first Pixar film to feature Michael Giacchino as composer.

Giacchino wrote the score for The Incredibles, released in 2004, using a big-band and spy-film sound influenced by mid-century superhero and espionage music. The score helped establish the film’s distinctive retro-futurist atmosphere and earned Giacchino an Annie Award for music in an animated feature.

He later composed the music for Pixar’s Cars, whose score combines orchestral writing with songs associated with American road culture. Giacchino also returned for Ratatouille, Up, and several other Pixar productions. Because his Pixar work spans multiple well-known films, Cars is sometimes incorrectly identified as his first Pixar score.

The Incredibles was directed by Brad Bird and became Pixar’s sixth feature film. Its story follows the Parr family, a group of superheroes living under civilian identities. Giacchino’s connection to Cars is therefore a neighboring franchise fact: he scored Cars after first working with Pixar on The Incredibles.
