Peter Cullen, the beloved voice actor who brought Optimus Prime to life in the Transformers franchise, has died at the age of 85. His passing marks the end of an era for animation and sci-fi fans worldwide.
Cullen's career began in Montreal, where he was born on July 28, 1941. He first made a name for himself in comedy television, appearing on shows like The Smothers Brothers Comedy Hour and The Sonny & Cher Comedy Hour. His deep, resonant voice quickly made him a sought-after announcer, leading him into the world of voice acting. Early roles included the villainous Venger in Dungeons & Dragons, the title monster's roars in the 1976 King Kong remake, and various characters in Voltron: Defender of the Universe.
In 1984, Cullen auditioned for what would become his defining role. Asked to voice the heroic Autobot leader Optimus Prime in The Transformers, he drew inspiration from his brother Larry, a Marine Corps captain. That personal touch gave Prime a noble, commanding presence that resonated with audiences. Cullen also voiced Ironhide, Prime's loyal aide, and went on to play the character in the animated series, the 1986 Transformers: The Movie, and seven live-action films starting in 2007. He even reprised the role in three later animated series.
One of the most memorable moments in animation history came when Optimus Prime was killed off in The Transformers: The Movie, voiced by Cullen's longtime friend Frank Welker as Megatron. The public outcry was so immense that Prime was quickly resurrected, a testament to the character's—and Cullen's—impact.
Beyond Transformers, Cullen created another iconic sound: the alien vocalizations for the Predator in the 1987 film Predator. Initially asked for roars and cries, Cullen's voice was strained from recording ape noises for King Kong Lives. After persistent requests, he saw the creature's design—which reminded him of an upturned horseshoe crab—and improvised the distinctive pops and clicks that have defined the Predator ever since.
Cullen also lent his voice to the morose Eeyore in The New Adventures of Winnie-the-Pooh and several subsequent projects. In recent years, he appeared in episodes of Prime Video's Invincible, once again alongside Welker. His work on that series is a reminder of his enduring relevance in modern animation.
Peter Cullen is survived by his four children and three grandchildren. His family confirmed he passed away at his home in Los Angeles, surrounded by loved ones. Fans and colleagues alike are mourning the loss of a true legend whose voice shaped countless childhoods.
For those looking to revisit Cullen's work, Prime Video's current lineup includes some of his later performances. His legacy also lives on in the adaptations that followed his pioneering voice work, and in the new sci-fi projects that owe a debt to his iconic roles.
Peter Cullen's voice was more than just sound—it was a source of inspiration, comfort, and heroism for millions. He will be deeply missed.
