Peter Cullen was a Canadian actor whose voice became familiar to audiences across several generations. He worked in television and animation from the 1960s onwards, first appearing in comedy and announcer roles before specialising in voice acting.
He was most closely associated with Optimus Prime, the principled leader of the Autobots in Transformers, a franchise about robots from another planet who can change into vehicles and machines. Cullen played the character in the original 1980s cartoon and returned for later films and television projects, giving the role a consistent sound over decades.
He also voiced Eeyore, the quiet, pessimistic donkey from Winnie the Pooh, for nearly 30 years. His other work ranged from science-fiction and action films to children’s cartoons, reflecting the wide reach of his career.
Full account
Peter Cullen, the Canadian actor whose voice became inseparable from Transformers leader Optimus Prime and Disney’s Eeyore, has died aged 85. A statement cited in one report said he died peacefully at his Los Angeles home on Wednesday, surrounded by family. Cullen’s career stretched from Canadian radio and television comedy to decades of animation, film and games, giving him an unusually broad presence across popular culture.
Born in Montreal, Quebec, Cullen began in Canadian broadcasting before appearing on US variety programmes, including work connected with The Smothers Brothers Comedy Hour and The Sonny & Cher Show. He increasingly concentrated on voice performance during the 1970s and 1980s. Early notable work included providing the sounds of King Kong in the 1976 film, K.A.R.R., KITT’s hostile counterpart in Knight Rider, and the distinctive vocal effects for the Predator in the 1987 film.
His defining role arrived with the original Transformers television series in 1984. Cullen later returned as Optimus Prime for the live-action films, appearing across seven releases between 2007 and 2023, as well as related productions. He said the character’s restrained authority came from his older brother Larry, a Vietnam veteran and Marine, whose advice was to portray a genuine hero as calm, compassionate and secure rather than loud or performatively tough. That principle, expressed as being “strong enough to be gentle”, became closely associated with Cullen and Optimus Prime.
Cullen also voiced Eeyore from the late 1980s in The New Adventures of Winnie the Pooh and numerous subsequent Disney productions, remaining in the part for nearly three decades. His other credits included Monterey Jack in Chip ’n Dale: Rescue Rangers and roles in series such as Spider-Man, Donkey Kong, Dungeons & Dragons, DuckTales, TaleSpin and Teenage Mutant Ninja Turtles. He continued working late in life, including Invincible, and received a lifetime achievement award at the Children’s & Family Emmy Awards in 2023.
