In Pixar's Cars (2006), Bob Costas voices the racing announcer Bob Cutlass.
Bob Cutlass is one of the commentators who covers the Piston Cup competition. His role helps make the fictional racing world feel like a televised sporting event, with pre-race discussion, live commentary, and analysis of the leading drivers. The character's name and delivery also echo real-world American sports broadcasting.
Bob Costas is a renowned American sportscaster known for covering major events across several sports. His appearance in Cars is a voice role rather than an on-screen performance. The film also features real racing personalities, including Darrell Waltrip, who voices the crew chief and commentator Darrell Cartrip.
Because both Costas and Waltrip are connected with sports broadcasting, viewers sometimes interchange their Cars characters. Bob Cutlass is the announcer paired with Darrell Cartrip in the racing coverage. The film's cast also includes Owen Wilson, Bonnie Hunt, Paul Newman, and Larry the Cable Guy.
