Peter Cullen, Voice of Optimus Prime in ‘Transformers,’ Dies at 85

Peter Cullen, the Canadian voice actor who starred as the heroic Optimus Prime in a convoy of Transformers films, TV shows and video games and as the gloomy Eeyore in dozens of Winnie the Pooh projects, has died. He was 85.

Cullen died Wednesday at his home in Los Angeles, his family announced.

The Montreal-born Cullen also voiced King Kong for the 1976 remake and the evil K.A.R.R. (short for Knight Automated Roving Robot) on Knight Rider series in 1982 and 2009, and he came up with the scary clicking sounds that emerged from the mouth of the monster in the Arnold Schwarzenegger -starring Predator (1987).

Early in his career, he was a live-action performer and served as the announcer for The Smothers Brothers Comedy Hour and The Sonny & Cher Comedy Hour .

In a 2014 NPR interview, Cullen noted that he initially approached playing Optimus Prime with puzzlement. “I auditioned like everybody else,” he said. “I was told it was a hero, and I was told it was a truck.”

The good-natured Cullen got the job and voiced the honorable leader of the Autobots for the first time on the 1984-87 syndicated series The Transformers , based on the Hasbro toy line and produced by Marvel in association with Toei Animation of Japan and then AKOM in South Korea.

Optimus’ death after a duel with the tyrannical Megatron in The Transformers: The Movie (1986) caused a huge and unexpected outcry, prompting producers to bring Cullen and the character back for the 1987 straight-to-video movie The Transformers: The Return of Optimus Prime .

When director Michael Bay resurrected the property for the big screen with DreamWorks’ Transformers (2007), starring Shia LaBeouf , it was a no-brainer to rehire Cullen after two decades away.

“I describe it as kind of slipping into an old pair of very comfortable shoes that you haven’t worn for a while,” he told IGN in 2007. “I just slipped right into them, and they felt as good as the last time I put them on.”

With Cullen as the Peterbilt 379 semi-trailer truck, the film grossed $709.7 million worldwide — the fifth-highest grossing movie of the year. He followed with the sequels Revenge of the Fallen (2009), which raked in $836.3 million, and Dark of the Moon (2011) and Age of Extinction (2014), which each raked in $1.1 billion.

Cullen also played Optimus in The Last Knight (2017), Bumblebee (2018) and Rise of the Beasts (2023). (Chris Hemsworth voiced the character in 2014’s Transformers One .)

Cullen began as the voice of Eeyore on the 1988-91 series The New Adventures of Winnie the Pooh , and he portrayed the droopy donkey in the feature Winnie the Pooh: A Very Merry Pooh Year (2002) and on other shows and videos.

“I get an awful lot of reactions from, especially, young kids, when I go up and just say [in Eeyore’s voice], ‘Hello. Thanks for noticing me,'” Cullen said.
