Cullen’s career spanned from being an announcer at the groundbreaking late-1960s comedy and variety series The Smothers Brothers Comedy Hour to The Smurfs and multiple G.I. Joe iterations, but he struck a nerve as Optimus Prime.

While the original cartoon ran just a few years, it left an indelible mark on pop culture, with a toy line, spinoff cartoon series and comics produced over the next two decades. That culminated in Michael Bay's launch of a multibillion-dollar live-action film franchise in 2007.

Before his audition, Cullen only knew that he would be reading for the part of a truck, though giving voice to a vehicle didn’t seem that crazy. “You’re always auditioning for something in animation that’s a little off of the norm,” Cullen told the AP in 2019.

When Cullen read about the heroic Autobot leader that turned into a red cabover semitrailer, he thought about his older brother, who had served as a U.S. Marine in the Vietnam War.

Cullen was best known for providing the deep, sonorous voice of Optimus Prime in both the Transformers film franchise and the popular animated TV series that began in the 1980s.

“He was my hero, and he certainly was the mainstay behind the character,” Cullen said. “I just did an impression of Larry, and he’s still alive in my mind today because every time I do Prime, there’s my brother Larry.”

Cullen’s authoritative baritone as Optimus Prime also appeared in 2009’s Transformers: Revenge of the Fallen through Dark of the Moon, Age of Extinction, The Last Knight, Bumblebee and Rise of the Beasts in 2023.

His thoughtful, almost operatic lines would be quoted for decades by kids and adults alike: “I am Optimus Prime, and I send this message to any surviving Autobots taking refuge among the stars: We are here. We are waiting,” he said in the first movie. In another, he intoned: “Fate rarely calls upon us at a moment of our choosing.”

Other highlights from Cullen’s prolific career include voicing Eeyore across various Winnie-the-Pooh projects, including Disney’s The New Adventures of Winnie the Pooh TV series that aired from 1988-91, as well as voicing the villainous KARR opposite KITT in the 1980s NBC series Knight Rider, and lending his pipes to King Kong in the Jeff Bridges-led King Kong remake in 1976.

Cullen would attend conventions around the country to meet with fans from multiple generations, often getting teary. He said parents sometimes got more excited than their children meeting him.

“I expect that I will run into a father with his son, and the father will more than likely get choked up,” Cullen said before MegaCon Orlando in 2019. “And then I get choked up, and then the kid is saying ‘What are these two grown men getting choked up about?’”

Cullen is survived by his four children, Angus, Claire, Pilar and Clay.
