P
eter Cullen died at home in Los Angeles on Wednesday. He was 85.
His agent, Kevin Motley, broke the news Thursday. By lunchtime it was everywhere. Hasbro's accounts, fan pages that hadn't posted in months, actors who'd worked with him twenty years ago and hadn't said his name in public since. No cause of death has come out yet, and honestly it might not, some families just don't share that part. What they did share was a statement, and it wasn't the usual line about flowers or private services. They asked people to go be decent to somebody. That was basically it.
"Be strong enough to be gentle." Apparently Cullen said that enough over the years that his own family used it to sum him up.
Think about that for a second, because it's a little wild when you sit with it. Most of the people mourning him online this week couldn't have picked Peter Cullen out of a lineup. But they've had his voice rattling around in their heads since they were kids. He was Optimus Prime, the one narrating giant robots pounding each other into scrap for four straight decades. He was also Eeyore. Gray, saggy, permanently a little bummed out, the low note in every scene he's in. Same guy. Same set of vocal cords, somehow doing both without either one feeling like a bit.
He was born in Montreal in 1941 to American parents, one of four kids in the family. Trained at the National Theatre School of Canada. Did a summer of Shakespeare up in Stratford, Ontario. Spent a year grinding through rep theater in Toronto. None of that exactly points toward giant robots. Cullen told NPR at some point that his whole ear for voices actually traces back to a farm, doing animal impressions as a kid because, well, there wasn't a lot else going on out there.
By the early '80s he'd landed in LA doing voice work, and in 1984 he walked into an audition for a cartoon tied to some toy line nobody had heard of. The briefing was not exactly detailed. "I was told it was a hero, and I was told it was a truck." That's it, that's the whole pitch he got. Somehow it turned into The Transformers, and his read on Optimus Prime, steady, warm, never once shouting to prove a point, hit so hard that basically every actor who's touched the role since has been compared to him and come up short.
Four seasons in, the show's animated movie killed Optimus off. And kids lost it. Not in a cute way either, actual letters, actual outrage. It worked. Producers pulled Cullen back a year later for a straight-to-video sequel with one job: undo what they'd just done to a generation of eight-year-olds.
Optimus went quiet for a long stretch after that. Cullen didn't, he just worked other rooms for a while. Then Michael Bay decided to turn the whole thing into a live-action blockbuster in 2007, and nobody seriously debated who'd voice the lead. Cullen stepped back in and said later it felt like digging an old pair of shoes out of the closet after two decades and wondering why he'd ever bothered getting rid of them.
From there the résumé basically writes itself: Revenge of the Fallen, Dark of the Moon, Age of Extinction, The Last Knight, the Bumblebee spinoff, 2023's Rise of the Beasts. He also did Optimus for the animated Transformers: Prime, which landed him a Daytime Emmy nomination in 2011, and for a stack of video games including the War for Cybertron trilogy. When the 2024 prequel Transformers One rolled around, Chris Hemsworth got the part instead. That's one of maybe two or three times in forty years the voice belonged to somebody else.
Ask Cullen which role he loved most and Eeyore usually came in second, right behind Optimus. He picked up the donkey in 1988's The New Adventures of Winnie the Pooh and just kept at it for decades: The Tigger Movie, Piglet's Big Movie, A Very Merry Pooh Year, on and on. His reasoning for loving the part was almost embarrassingly simple. Eeyore was charming. Kids would light up when he did the voice for them in person. That reaction, he said, was one of the genuine highlights of his whole career.
And there was a lot more where that came from. He did the clicking, growling sound effects for the creature in Predator. He voiced K.A.R.R., the evil car, on Knight Rider. He was King Kong in the 1976 remake. He played Monterey Jack on Chip 'n Dale: Rescue Rangers. Later in life he popped up as Thaedus on Prime Video's Invincible, a much colder, harder role than fans were used to hearing from him, and the show's account posted a tribute within hours of the news breaking Thursday.
He got inducted into the Transformers Hall of Fame back in 2010, and picked up a Lifetime Achievement Award at the Children's and Family Emmy Awards in 2023. Not a bad run for somebody who, by his own telling, more or less backed into the whole career doing bird noises on a farm.
Cullen is survived by his family. Instead of flowers, they've asked people put that energy toward their own communities.
Peter Cullen, who voiced Optimus Prime across nearly every Transformers cartoon, film and game since 1984 and played Eeyore in a string of Winnie the Pooh productions, died Wednesday at his home in Los Angeles. He was 85. His agent confirmed the death; no cause has been released.
