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


Canadian voice actor Peter Cullen, renowned for his deep-voiced portrayal of Optimus Prime in the 1984 Transformers series and for voicing the melancholic donkey Eeyore in Winnie the Pooh, has died at the age of 85. He began his career in Canadian television and radio before turning to voice‑acting, where he left an unforgettable imprint on popular animated franchises.

Cullen’s voice work extended beyond Transformers: he voiced the villainous KARR in the TV series Knight Rider, the iconic Predator in the 1987 film, and even the roaring King Kong in the 1976 movie. He also supplied the voice of Monterey Jack in Chip 'n Dale Rescue Rangers and lent his talent to beloved shows such as Spider‑Man, Donkey Kong, Alvin & the Chipmunks, Dungeons & Dragons, My Little Pony, Duck Tales and Gummi Bears.


After a successful screen life, Cullen was honored at the Children’s & Family Emmy Awards in 2023 with a lifetime‑achievement award. His career earned him a Daytime Emmy nomination in 2011 for Outstanding Performer in an Animated Program.


The artist died Wednesday at his Los‑Angeles home, surrounded by family. A statement released by his representatives read: Peter Cullen passed away peacefully and will be remembered in the hearts of fans worldwide. The family respectfully asks that his community carry forward his legacy by serving others with compassion, integrity, and loyalty, remembering always to be strong enough to be gentle.


A key influence on Cullen’s Optimus Prime vocal style came from his older brother, a decorated U.S. Marine and Vietnam War veteran who encouraged him to portray the character as a genuine hero rather than a Hollywood trope. He advised: Don’t simply yell and scream; a hero can be gentle yet mighty. This philosophy became the cornerstone of Cullen’s iconic performance.
