When you sit down to watch Cars, there’s a specific moment where the vibe shifts. It’s when we first meet the crusty, mysterious judge of Radiator Springs. That gravelly, "seen-it-all" voice doesn’t just sound like an old car; it sounds like history. That’s because the Doc Hudson voice actor was none other than Paul Newman. Honestly, calling him just a "voice actor" feels like a bit of an undersell.
Newman wasn’t just some Hollywood A-lister doing a cartoon for a paycheck. He was a racing fanatic. He lived for the track. By the time Pixar came knocking, Newman had already won national championships and even took second at Le Mans. So, when he spoke as the Fabulous Hudson Hornet, he wasn’t just reading lines. He was talking about a life he actually lived.
The Legend Behind the Hood
Paul Newman’s casting was a massive win for Pixar. John Lasseter, who directed the first film, basically tailored the character to fit Newman’s personality. Newman was notoriously picky about his later roles, but the idea of playing a retired 1951 Hudson Hornet—a car with a real-world racing pedigree—hooked him.
He didn't just show up to the recording booth and leave. He spent hours talking to the crew about horsepower, suspension, and the "dirt track" mentality. Most people don't realize that some of Doc's best lines weren't even in the script. Lasseter kept the microphones running while Newman just told old racing stories. Those "off-the-cuff" moments provided the soul of the character.
What Happened After Paul Newman Passed?
This is where things got tricky for Pixar. Paul Newman died in September 2008, just two years after the first movie came out. He was 83. The industry usually just recasts these roles. Look at Slinky Dog; after Jim Varney passed, they brought in Blake Clark. But Doc Hudson was different.

Pixar decided that Doc Hudson was Paul Newman. They felt that replacing that iconic voice would be a disservice to the man and the mentor-student bond he built with Lightning McQueen. So, for Cars 2 in 2011, they made a bold choice. They killed off Doc Hudson.
Well, "killed off" is a harsh way to put it. They retired him. The Piston Cup was renamed the Hudson Hornet Memorial Piston Cup. His clinic became a museum. It was a class act. They acknowledged the loss of the actor by acknowledging the loss of the character. Fans were split, though. Some missed the Doc-McQueen dynamic, while others appreciated the respect shown to Newman's legacy.
The Resurrection in Cars 3
If you watched Cars 3, you might have been confused. Doc Hudson is all over that movie. You hear his voice, clear as day, giving McQueen advice about aging and finding a new purpose. No, they didn't use AI—at least not in the way we think of it today.
Pixar went back to those old tapes from 2006. Remember how I said Lasseter kept the mics running during Newman's racing stories? They mined those archives for every scrap of dialogue they could find. They found an unused monologue where Newman talked about racing being "one lap after another, inches apart."

It was haunting. It was beautiful. By using real, archival recordings, they brought the Doc Hudson voice actor back for one last ride without having to hire a sound-alike for the theatrical film. It gave the movie a weight that a replacement actor just couldn't have carried.
The "Other" Doc Hudsons
Now, if you’ve played the video games or visited the theme parks, you might notice something. Doc sounds... slightly different. Since you can't build a whole video game or a permanent Disney World attraction off of 20-year-old outtakes, Pixar did eventually have to find a "utility" voice.
Enter Corey Burton.
Burton is a legendary voice actor—you probably know him as Count Dooku or Cad Bane from Star Wars. He’s a master of mimicry. He took over the role for:

Burton does an incredible job capturing the "sandpaper and silk" texture of Newman’s voice, but even he would likely tell you that he’s just keeping the seat warm. He’s the bridge that keeps the character alive for kids at the parks, while Newman remains the definitive voice for the films.
Why Doc Hudson Still Matters
Why are we still talking about a cartoon car from 2006? Because the casting of the Doc Hudson voice actor represented a shift in how animated movies handled "celebrity" voices. It wasn't about marketing a big name; it was about finding the one person on Earth who understood the character's DNA.
Doc Hudson wasn't just a mentor to Lightning McQueen. He was a mirror for Paul Newman’s own life—a man who found more joy in the smell of gasoline and burnt rubber than in the glitz of Hollywood.
