The short version

  • Peter Cullen, the voice behind Optimus Prime in Transformers and Eeyore in Winnie the Pooh, has died at age 85.
  • Cullen’s career spanned Canadian television, radio, and major Hollywood franchises including Knight Rider, Predator, and King Kong.
  • His portrayal of Optimus Prime was inspired by his brother, a Marine veteran, who advised him to be 'strong enough to be gentle.'

Peter Cullen, the distinguished voice actor whose deep, authoritative baritone defined generations of animated characters, has died at the age of 85. He passed away peacefully on Wednesday at his home in Los Angeles, surrounded by family, according to a statement released by his loved ones. Cullen was best known for voicing Optimus Prime, the heroic leader of the Autobots in the Transformers franchise, and Eeyore, the melancholic donkey in Disney’s Winnie the Pooh series.

Born in Montreal, Cullen began his career in Canadian television and radio before transitioning to voice acting as his primary focus. His early work included regular appearances on variety programs such as The Sonny & Cher Show and The Smothers Brothers Comedy Hour. However, it was his ability to inhabit complex characters through sound alone that cemented his place in entertainment history. He brought a distinctive gravitas to Optimus Prime starting with the original 1984 animated series, a role he reprised for seven Hollywood films between 2007 and 2023, as well as numerous spinoffs.

News Journal

Cullen’s approach to Optimus Prime was deeply personal. He credited his older brother Larry, a retired captain in the US Marine Corps who served in the Vietnam War, with shaping the character’s voice. Larry advised Cullen to portray the robot not as a shouting Hollywood hero, but as a genuine leader who was 'strong enough to be gentle.' Cullen recalled hearing his brother’s voice during auditions, finding the character’s seriousness and authority in that quiet strength. In a gesture of gratitude, Cullen gave Larry a portion of his wages for playing Optimus Prime until his brother’s death in 2011.

Beyond Transformers, Cullen’s vocal range was extensive. He voiced Eeyore in The New Adventures of Winnie the Pooh from the late 1980s onward, bringing warmth to the character’s gloom. His film credits included providing the roars for King Kong in the 1976 remake and creating the eerie clicking sounds for the monster in Arnold Schwarzenegger’s 1987 film Predator. He also voiced KARR, the evil counterpart to KITT, in the Knight Rider series during its original run and a 2009 revival.

His contributions to animation were recognized with industry honors, including a Daytime Emmy nomination for outstanding performer in an animated program in 2011. In 2023, he received a lifetime achievement award at the Children’s & Family Emmy Awards. Cullen also lent his voice to characters in popular series such as Chip 'n Dale Rescue Rangers, Spider-Man, Donkey Kong, Alvin & the Chipmunks, Dungeons & Dragons, My Little Pony, DuckTales, and Gummi Bears.

Cullen initially approached the role of Optimus Prime with some uncertainty. In a 2014 interview, he noted that he was told the character was simply 'a hero' and 'a truck,' requiring him to find depth in minimal direction. When director Michael Bay revived the franchise for film in 2007, Cullen described returning to the role as slipping into comfortable shoes he had not worn in years.

The family’s statement asked fans to honor Cullen’s remarkable legacy by serving their communities and leading with compassion, integrity, and loyalty. They urged people to remember his guiding principle: 'be strong enough to be gentle.' Cullen is survived by his family and remembered by countless friends and fans worldwide who grew up listening to his voice.

His death marks the end of an era for voice acting, particularly in the realm of animated heroes and villains. From the Canadian airwaves to global box office hits, Cullen’s work influenced how audiences perceived strength and vulnerability in character performance. His ability to convey emotion through tone alone set a standard for the craft.

As tributes pour in from colleagues and fans, the focus remains on the impact of his characters. Optimus Prime and Eeyore remain cultural touchstones, their voices inseparable from Cullen’s performance. The entertainment industry has lost one of its most versatile and respected voice talents, whose work will continue to resonate with new generations.

Cullen’s career serves as a testament to the power of voice acting in storytelling. By infusing fictional characters with humanity and depth, he helped define the emotional landscape of modern animation and film. His legacy endures not just in the roles he played, but in the values he embodied both on and off screen.
