Harv is a minor antagonist in the 2006 film, Cars. He is Lightning McQueen's agent. He is portrayed as a strict figure that does not allow any nonsense, often scolding his clients if they try to focus on anything other than racing. Never seen on-screen, McQueen speaks to Harv via his speakerphone in Cars when he and Mack are on route to the tiebreaker race, and again when Mack is in Radiator Springs to pick up McQueen. Consequently, little is known of Harv's character except that he threatened to stop supporting Mack if he didn't get McQueen into his trailer when he is in the town.
