Which actor voices Sterling, McQueen’s sponsor, in Pixar’s Cars 3?

Nathan Fillion voices Sterling, McQueen’s sponsor, in Pixar’s Cars 3.

Sterling is the wealthy owner of the Rust-eze racing team in Cars 3. He hires Cruz Ramirez to train Lightning McQueen after a new generation of technologically advanced racers threatens Lightning’s career. Sterling’s business goal is to turn the Rust-eze brand into a profitable modern racing operation.

Nathan Fillion is known for television roles including Richard Castle in Castle and John Nolan in The Rookie. His voice performance gives Sterling a polished, confident executive personality that contrasts with Lightning’s uncertainty about the future.

Sterling is separate from Rusty and Dusty Rust-eze, the brothers who originally sponsor Lightning in the franchise. Those characters are voiced by Tom and Ray Magliozzi, while Fillion voices the later team owner introduced in Cars 3.
