Peter Cullen Is A Machine... Also A Donkey

Most Transformers fans will agree that Peter Cullen is the only true voice of Optimus Prime. But there's a good chance that you've heard him in other shows and didn't even know it was him!

  • K.A.R.R.


    In two episodes of the 80s TV show Knight Rider, Peter Cullen voiced K.A.R.R., sort of an evil twin to the artificially intelligent Pontiac Trans Am, K.I.T.T. Cullen later reprised the role for the 2009 Knight Rider reboot.

    Cast as the original voice of Autobot leader Optimus Prime in the 1984 animated Transformers series, Cullen reprised the role numerous times thereafter, including the recent trilogy of Michael Bay movies.

  • Gobots


    In order to compete with Hasbro's Transformers success, Tonka released their own morphing robot vehicle line of toys with promotional animated series known as Gobots. As though the entire concept wasn't similar enough, Peter Cullen was also cast to voice Spoiler, Tank, and Pincher.

  • Voltron Narrator

    There's no question in my mind that if Voltron could speak, he would sound exactly like Optimus Prime. But since Voltron is only a machine piloted by five distinct characters, Peter Cullen voiced the show's narrator in addition to the characters of King Alfor and Coran.

  • Eeyore


    Voicing awesome mechanical men isn't all that Peter can do. He's also played Pooh Bear's perpetually depressed, probably suicidal friend Eeyore in 11 films and at least three Disney television series.
