Yup, Canadian-born Maurice LaMarche (born March 30, 1958) is best known for the voice of The Brain in Pinky and the Brain. In creating that voice, LaMarche said he looked at a picture of the character and immediately thought of Orson Welles, although the character wasn't modeled after Welles at all, and he made use of his signature impersonation of Welles as a result — many Pinky and the Brain episodes are nods to Welles' career, actually. The role also earned LaMarche an Annie Award.
He also has roles in many commercials, including (since 2009) that of the narrator for Lexus TV ads and Toucan Sam in the Froot Loops commercials after Paul Frees' death in 1986.
Some of Maurice LaMarche's more prominent roles include:
- Dishonest John in the 1988 revival of Beany and Cecil.
- Simion the Monkey on Dexter's Laboratory.
- The Brain, Squit (the Ray Liotta-esque pigeon who wants to be a Goodfeather) and the Godpigeon in Animaniacs and Pinky and the Brain. Speaking of Animaniacs, Wakko's burps were performed by LaMarche.
- Chief Quimby in the second season of Inspector Gadget
- LaMarche also plays Gadget himself. He got his start as Don Adams' singing double in Inspector Gadget Saves Christmas, and started doing the voice proper in Inspector Gadget's Last Case and continued in Gadget and the Gadgetinis. He also played the character onscreen for Gadget's appearance on The Super Mario Bros. Super Show!.
