LaMarche began on Inspector Gadget and went on to Dennis the Menace, Popeye and Son and The Real Ghostbusters. After The Real Ghostbusters, LaMarche became a regular mainstay of the voiceover industry appearing in such shows as Tiny Toon Adventures, GI Joe, Attack of the Killer Tomatoes: The Animated Series, Taz-Mania, Where's Waldo, The Little Mermaid, Batman: The Animated Series, and Bonkers before landing perhaps his most recognized role in 1993 as The Brain on Animaniacs (and later its spin-off show Pinky and the Brain).
Following this, LaMarche worked on The Critic, Freakazoid!, and The Tick before then reprising his role of Egon in Extreme Ghostbusters. The stretch of two years after this saw LaMarche portray characters in such shows as Hey Arnold! as Big Bob Pataki, Queer Duck, The Chimp Channel, and Sonic Underground as Sleet. During this time Maurice would become the voice actor for Mortimer Mouse who he would voice in the television series Mickey Mouse Works and Disney's House of Mouse. It was at this time, 1999, that LaMarche began work on Futurama, and since Futurama LaMarche has continued to work steadily in television, including guest roles on The Simpsons (where he once again parodied Orson Welles). His most recent regular role came as Hovis the butler on the Nickelodeon series Catscratch. LaMarche was the voice of Victor in Playhouse Disney's Handy Manny Halloween episode.
LaMarche has done various voice work for many Warner Bros. Animation and DiC Entertainment cartoons. He also delivered the protracted belches for the "Great Wakkorotti" shorts on Animaniacs, in which Wakko Warner performed various pieces of music. In 2011, LaMarche reprised his role as Yosemite Sam in Cartoon Network's new series The Looney Tunes Show.
