Peter Cullen, voice of Optimus Prime and Eeyore, dies at 85

Death confirmed by family and agent

Peter Cullen, the prolific voice actor who gave Optimus Prime his authoritative baritone in the "Transformers" franchise and voiced Eeyore across multiple "Winnie the Pooh" projects, has died at 85. His agent, Kevin Motley, told The Associated Press and the Los Angeles Times that Cullen died Wednesday at his home in Los Angeles; a cause of death was not given. The family said he "passed away peacefully, surrounded by his loving family — and held in the hearts of his many friends and countless fans worldwide," and asked that his legacy be honored by "serving your communities and leading others with compassion, integrity, and loyalty and always remember 'be strong enough to be gentle.'"

A four-decade run as Optimus Prime

Cullen first voiced Optimus Prime in the syndicated 1984 "Transformers" series after auditioning for what he initially knew only as "the part of a truck." He told the AP in 2019 that he based the character on his older brother Larry, a U.S. Marine who served in Vietnam, calling Larry "my hero" and "the mainstay behind the character." His performance anchored the original cartoon, its spinoff series, a sprawling toy line, and the multibillion-dollar live-action film franchise that launched in 2007 under director Michael Bay. Cullen reprised the role through "Transformers: Revenge of the Fallen" (2009), "Dark of the Moon," "Age of Extinction," "The Last Knight," the prequel "Bumblebee," and 2023's "Rise of the Beasts," delivering lines that became cultural touchstones, including "I am Optimus Prime" and "Fate rarely calls upon us at a moment of our choosing."

Range beyond Prime: Eeyore, G.I. Joe, Knight Rider

Beyond Optimus Prime, Cullen's "thoughtful, almost operatic" voice populated a wide range of animation and television. He voiced Eeyore in Disney's "The New Adventures of Winnie the Pooh" (1988–91) and other Pooh projects, told the New York Times in 2008 that Optimus was his favorite role but that Eeyore had "had a considerable effect on younger children too." He voiced the villainous KARR opposite KITT on NBC's 1980s "Knight Rider," contributed to multiple "G.I. Joe" iterations and "The Smurfs," and served as an announcer on "The Smothers Brothers Comedy Hour" in the late 1960s before joining comedy sketches for Sonny & Cher. He also provided vocal effects, including the clicking sound for the 1976 "King Kong" remake led by Jeff Bridges.

Legacy

Cullen became synonymous with Optimus Prime across roughly four decades of animation, film and merchandise, and his death marks the passing of a voice that defined two of the most recognizable characters in modern American pop culture. The AP obituary noted that his "authoritative baritone" and his character quotes were repeated by "kids and adults alike," underscoring how fully his vocal performance became inseparable from the Autobot leader himself.
