Peter Cullen
Peter Cullen is an actor, born 1941.
Cullen was a jobbing Canadian voice actor with a low, unhurried baritone when he was cast as Optimus Prime in the 1984 Transformers series. The same decade brought Eeyore in Disney's Winnie the Pooh cartoons, Monterey Jack in Chip 'n Dale Rescue Rangers, the first voice of KARR on Knight Rider, and the uncredited vocal effects for the creature in Predator. The 1976 King Kong remake and Gremlins also run on his throat.
What makes him unusual is that he plays sincerity without a hint of irony. Optimus Prime is a cartoon designed to sell trucks, and Cullen reads every line as though the character genuinely believes what he is saying, which is why children took it seriously and why grown adults still do. Eeyore is the same trick inverted: the gloom is played completely straight and the comedy comes from everyone around him.
The 2007 live-action Transformers brought him back after two decades away from the part, and he has voiced it in every sequel since, including Bumblebee and Rise of the Beasts. That is remarkable longevity for a franchise voice, and it is worth saying plainly that the films are frequently poor while the voice never is. Recent work includes Thaedus in Invincible, which uses the same authority for a character with considerably less faith in it.

Where to start with Peter Cullen
Chronology is the right approach. The Transformers from 1984 is where Optimus Prime gets invented, and an episode or two is worth it even if the animation defeats you, because the voice arrives fully formed. The Transformers: The Movie in 1986 is the one that scarred a generation and is still the best-directed thing in the franchise.
Then jump to Transformers for the return, and Bumblebee, the only live-action entry that treats the character with any care at all. Away from the robots, Predator is him making noises that people are still copying, Gremlins works the same range, and The New Adventures of Winnie the Pooh has his Eeyore, which is the opposite skill entirely. Treasure Planet gives him a proper villain. INVINCIBLE is the recent one and the easiest place to hear how little the instrument has aged.
Optimus Prime, across forty years
He based the voice on his brother, a marine who said a real hero is quiet and gentle, and that single decision is why a toy commercial produced a character people still get emotional about. The 1986 animated film is the one that traumatised a generation.
The other Cullen voices you already know
The same instrument used for the opposite purpose: the Predator's clicking growl, Eeyore's flat resignation, and a long run of eighties creatures. Hearing Predator and Eeyore back to back is the fastest way to understand the range.
The eighties cartoons that built the career
Before the blockbusters he was everywhere in American syndicated animation, alongside the same small pool of actors who defined that decade. DuckTales, Rescue Rangers and the original Turtles are the run most viewers absorbed without ever reading a credit.
