Peter Cullen, Voice of Optimus Prime and Eeyore, Dies at 85


Peter Cullen, the Canadian actor who gave life to Optimus Prime in the original Transformers TV series and to the melancholy donkey Eeyore in Disney’s Winnie the Pooh franchise, died at his Los Angeles home on August 27, 2026.


Cullen began his career on Canadian radio and television and then focused on voice acting. He first voiced Optimus Prime in 1984 for the animated series and later returned to the role for seven Hollywood Transformers films from 2007 to 2023. The deep, steadfast tone he used for the heroic leader has become a touchstone for fans of the franchise.


Legacy and Awards


Throughout his life Cullen’s work spanned animated series such as Chip 'n Dale Rescue Rangers, Spider‑Man, Donkey Kong, Alvin & the Chipmunks and Duck Tales, as well as video games and film. In 2011 he earned a Daytime Emmy nomination for outstanding performer in an animated programme. In 2023 he was honored with a lifetime achievement award at the Children’s & Family Emmy Awards recognizing his contributions to family entertainment.


Brother’s Guidance


Cullen credited the inspiration for his Optimus Prime performance to his older brother, a decorated U.S. Marine who served in the Vietnam War. The veteran urged him to portray the character as “a real hero, not a Hollywood hero.” The phrase “He is strong enough to be gentle” became a guiding principle that distinguished Cullen’s voice.


Cullen is survived by his family, who shared a statement announcing his peaceful passing and described him as a beloved figure whose legacy urges fans to act with compassion and integrity. The message echoed his own words: be strong enough to be gentle.


“Peter Cullen passed away peacefully, surrounded by his loving family – and held in the hearts of his many friends and countless fans worldwide.”
