Peter Cullen, the voice actor whose deep, steady baritone gave life to Optimus Prime across four decades of Transformers films, TV series, and video games, has died at 85.
Cullen's agent, Kevin Motley, confirmed the actor died Wednesday, August 26, at his home in Los Angeles. A cause of death has not been disclosed.
"Peter Cullen passed away peacefully, surrounded by his loving family - and held in the hearts of his many friends and countless fans worldwide," his family said in a statement. They asked fans to "honor his remarkable legacy by serving your communities and leading others with compassion, integrity, and loyalty," closing with a phrase Cullen lived by: "Be strong enough to be gentle."
Born Peter Claver Cullen on July 28, 1941, in Montreal, Canada, he was raised in the Catholic faith and attended Regiopolis-Notre Dame Catholic Secondary School before training at the National Theatre School of Canada. His middle name, Claver, honored St. Peter Claver, a detail that friends say quietly shaped the humility and gentle strength he brought to every role.
Cullen first voiced Optimus Prime in the original 1984 Transformers animated series, later reprising the role throughout Michael Bay's live-action franchise. He said he drew the character's calm authority from his older brother Larry, a U.S. Marine Corps veteran - the same "strong enough to be gentle" philosophy his family echoed in their farewell statement.
Beyond Transformers, Cullen voiced Eeyore in Winnie the Pooh, created the Predator's iconic clicking sounds, and racked up more than 200 credits across a 60-year career. He received a Lifetime Achievement Award from the National Academy of Television Arts and Sciences in 2023.
His family's final request wasn't for tributes, but for something simpler: to carry his values forward.
