Peter Cullen, the iconic voice behind Optimus Prime in the "Transformers" franchise, has died at the age of 85. His death certificate, obtained by TMZ, lists cardiac arrest due to respiratory arrest as the cause, with a malignant neoplasm in the lower lobe of his lungs as the underlying cause. Cullen passed away peacefully at his Los Angeles home on August 26.
Cullen's career spanned decades, with his signature deep baritone bringing the Autobots leader to life in the original 1980s animated series and its 1986 film adaptation. He reprised the role for every live-action "Transformers" movie, beginning with Michael Bay's 2007 film. He also lent his voice to other memorable characters, including Eeyore in "The New Adventures of Winnie the Pooh" and King Kong in the 1976 film "King Kong."
In 2023, Cullen received a Lifetime Achievement Award at the Children’s & Family Emmy Awards for his contributions to voice acting. During his acceptance speech, he revealed that the inspiration for Optimus Prime's voice came from his late brother, Larry, a decorated U.S. Marine Corps captain. Cullen shared his brother's advice: "Peter if you’re going to be a hero, be a real hero. Be strong enough to be gentle."
Cullen's family stated that he died "peacefully, surrounded by his loving family — and held in the hearts of his many friends and countless fans worldwide." They requested that his legacy be honored by serving communities with compassion, integrity, and loyalty.
Cullen is scheduled to be buried at Forest Lawn on September 9.
