Francis Lax

Not a cowboy. Or a scoundrel.

Francis Lax voiced Optimus Prime, Ironhide, Jazz, and Bumblebee in the French-dub version of the G1 cartoon.

He gave his voice for an impressive list of characters and actors, including Tom Selleck in Magnum, P.I., Harrison Ford in the Star Wars trilogy and Indiana Jones and the Temple of Doom, Jon Voight (but not in the movie) , and that hippie in Scooby-Doo. Bumblebee kinda sounded like him, actually. Weird.

Similarly, his interpretation of Optimus Prime may sound like "Howling Mad" Murdock imitating Peter Cullen.
