Veteran voice actor Peter Cullen, best known as the deep-voiced leader Optimus Prime in the Transformers franchise and the melancholic donkey Eeyore in Winnie the Pooh adaptations, has died at the age of 85, a statement reported on Wednesday said.
Long career, iconic characters
Cullen began voicing Optimus Prime for the Transformers television series in 1984. He later returned to the role for seven Hollywood films spanning 2007 to 2023, and voiced the character in several spin-offs and related productions, the reporting said. He also provided the voice of Eeyore in The New Adventures of Winnie the Pooh from the late 1980s and in numerous related programmes, films and games.
Beyond those two signature parts, Cullen’s work included a range of memorable contributions in film and television: the evil counterpart KARR in Knight Rider, the clicking vocalisations of the alien in The Predator (1987) and the roars of King Kong in a 1976 production, according to the report.
Family statement and inspiration
The statement said Cullen died at his home in Los Angeles, surrounded by family. It asked that fans "honour his remarkable legacy by serving your communities and leading others with compassion, integrity, and loyalty" and reiterated a guiding phrase Cullen had often credited for shaping his signature Optimus Prime voice.
"Be strong enough to be gentle."
Cullen had said his portrayal of Optimus Prime was inspired by his older brother, a decorated US Marine and Vietnam War veteran, who encouraged him to play the hero as a true, reserved figure rather than a loud, theatrical one. Cullen told interviewers that his brother advised: "Don't go yelling and screaming. He's strong enough to be gentle," guidance that he said resonated during auditions and performances. He also reportedly shared a portion of his wages for the role with his brother until the latter’s death.
Accolades and legacy
Recognition for Cullen’s contributions included a lifetime achievement award at the Children’s & Family Emmy Awards in 2023 and a Daytime Emmy nomination for outstanding performer in an animated programme in 2011, the report said. His death prompted tributes from fans and peers who noted the warmth and gravitas of his performances across generations.
His career trajectory began in Canadian television and radio. He later moved into regular appearances on shows such as The Sonny & Cher Show before focusing on voice work, where his vocal range and character instincts made him a sought-after performer in animation, film and games.

Cullen’s performances helped define several franchises and left an audible imprint on popular culture. Fans across age groups will recall the contrast between Optimus Prime’s resolute moral authority and Eeyore’s plaintive melancholy — a range that demonstrated Cullen’s versatility in bringing animated figures to life.
The family’s request that people honour Cullen’s legacy through service and compassion frames the end of his life as one marked by humility and quiet principle, mirroring the qualities he gave to some of the most enduring characters in animation and blockbuster cinema.
