In Pixar’s Cars 2, Mater becomes involved with the spy agency C.H.R.O.M.E.
The agency recruits Mater after secret agent Finn McMissile and spy-in-training Holley Shiftwell mistake him for an American agent. Mater’s accidental involvement turns the sequel into an international espionage adventure rather than a story focused only on racing and Radiator Springs.
C.H.R.O.M.E. is an acronym used for the fictional organization in the film. The agency’s work connects the plot’s races, the World Grand Prix, and a conspiracy involving alternative fuel. Mater’s lack of spy experience creates much of the comedy, while his honest observations help uncover information that trained agents overlook.
Cars 2 was directed by John Lasseter and Brad Lewis and released in 2011. The film’s expanded cast includes Michael Caine as Finn McMissile and Emily Mortimer as Holley Shiftwell, alongside the returning Mater and Lightning McQueen.
