Peter Cullen is a Canadian voice actor widely celebrated for his iconic portrayal of Optimus Prime across the long-running “Transformers” animated and live-action film and television franchise. Born in Montreal, Peter Cullen was part of the inaugural graduating class at the prestigious National Theatre School of Canada. Though he received classical training in theater, Peter Cullen shifted his focus toward voice acting in the early 1980s, where he began gaining recognition through roles on several French-Canadian children’s programs. His talent didn’t go unnoticed for long—soon, major American studios started reaching out, leading to a flood of opportunities in animation.
Over the years, Peter Cullen lent his distinctive voice to countless characters, but one of his most notable early roles was as Eeyore, the perpetually gloomy donkey, in “The New Adventures of Winnie the Pooh.” Since 1988, Peter Cullen has reprised this role across numerous Pooh-related films and TV series, endearing himself to generations of fans. Still, it’s his legendary performance as the noble Autobot leader, Optimus Prime, that truly defined his career. When the original animated series “The Transformers” debuted, Peter Cullen’s deep, resonant, and emotionally rich voice brought an unmatched gravitas to the character.
That portrayal became so iconic that Peter Cullen was invited back for nearly every adaptation that followed. He returned for the 1986 animated feature “The Transformers: The Movie,” and decades later, director Michael Bay personally selected Peter Cullen to voice Optimus Prime in the blockbuster live-action films, including “Transformers” (2007) and its sequel “Transformers: Revenge of the Fallen” (2009). Through each iteration, Peter Cullen’s voice remained synonymous with leadership, courage, and integrity—proving time and again why he remains one of the most respected figures in voice acting.
When it comes to Peter Cullen’s filmography, one standout in terms of critical acclaim is Bumblebee from 2018—it’s widely regarded as Peter Cullen’s highest rated movie. Fans and critics alike have praised the film for its emotional depth and nostalgic tone, which certainly added to its strong reception. On the other end of the spectrum, Peter Cullen’s lowest rated film appears to be Rainbow Brite and the Star Stealer, released way back in 1985. While it has a certain charm for some longtime fans, it didn’t quite resonate with broader audiences or reviewers at the time. So, when you look at the range of Peter Cullen’s work across decades, it’s interesting to see how his roles span such varied successes—Peter Cullen truly has been part of some memorable cinematic moments, both high and low.
