The Incredibles is a 2004 Pixar animated film directed by Brad Bird about the Parr family, a household of superheroes forced out of retirement. Its score by Michael Giacchino used big band brass and 1960s spy movie styling, giving the movie a musical identity that stood apart from other animated releases. Short excerpts from that heroic theme later circulated online as reaction audio, where creators borrow the film's sense of triumph for jokes, edits and introductions that need instant superhero energy without using a full song.
