Peter Cullen, the Canadian voice actor celebrated worldwide for giving Optimus Prime his unmistakable deep voice, has died at the age of 85.
Cullen reportedly passed away peacefully at his Los Angeles home on Wednesday, with members of his family by his side. His family later confirmed the news in a statement, asking admirers to remember the actor not only for his legendary work but also for the values he represented.
“His family asks that you honour his remarkable legacy by serving your communities and leading others with compassion, integrity, and loyalty and always remember ‘be strong enough to be gentle,'” the statement read.
Cullen’s iconic Optimus Prime voice
Cullen became the original voice of Optimus Prime when the Transformers animated series debuted in 1984.
He would go on to reprise the character decades later, lending his voice to seven major Transformers films released between 2007 and 2023, alongside several spin-off productions.
Interestingly, the qualities that became synonymous with Optimus Prime were inspired by Cullen’s own family.
The actor previously revealed that his older brother, a decorated US Marine and Vietnam War veteran, played an important role in shaping the character’s voice.
“He said, ‘Don’t go yelling and screaming. He’s strong enough to be gentle,'” Cullen recalled of his brother’s advice.
“And that resonated with me, and I could hear his voice all the way to the audition. When he drops down, when he gets serious, is where I found Optimus Prime.”
Cullen valued his brother’s influence so deeply that he shared part of the income he earned from the Optimus Prime role with him for the rest of his life.
His portrayal of the character earned him a Daytime Emmy nomination for outstanding performer in an animated programme in 2011. In 2023, Cullen was also honoured with a lifetime achievement award at the Children’s & Family Emmy Awards.
A career that spanned decades
Although Optimus Prime became his most famous role, Cullen’s career extended across numerous television shows, films and animated productions.
He was also widely recognised as the voice of Eeyore in The New Adventures of Winnie the Pooh, beginning in the late 1980s. He continued portraying the beloved donkey in related productions, including films and video games.
His other notable credits included KARR, the menacing counterpart to KITT in Knight Rider, as well as the distinctive vocal sounds of the Predator in Arnold Schwarzenegger’s 1987 film.
Cullen also provided the roar of King Kong in the 1976 movie.
His extensive animation résumé included Monterey Jack in Chip ‘n Dale: Rescue Rangers, as well as roles in popular productions such as Spider-Man, DuckTales, My Little Pony, Dungeons & Dragons, Alvin & the Chipmunks and Gummi Bears.
Cullen began his career in Canadian radio and television before appearing on mainstream programmes including The Sonny & Cher Show. He eventually dedicated himself primarily to voice acting, building a career that would span generations.
His death marks the passing of one of the most recognisable voices in animation, with his portrayal of Optimus Prime remaining a defining part of the Transformers franchise.
