How a Young Canadian Actor Created the Voice That Defined a Generation
Born in Montreal, Quebec, in July 1941, Cullen started his entertainment career in live-action television and comedy before finding his true calling behind the microphone. His journey into the world of voice acting began in earnest during the early 1980s when casting directors searched for a voice that could anchor a massive toy-line adaptation produced by Hasbro and Marvel Productions.

That creative choice transformed a red-and-blue semi-truck into one of the most revered fictional characters in modern history. Viewers tuned in week after week not just for the robot combat, but for the philosophical guidance Optimus Prime offered at the end of every episode.
