Personal life

Richard Steven Horvitz Richard Horvitz Talking Voices Part 1 YouTube

Horvitz was born, grew up, resides and currently works in Los Angeles. Later, he taught voice acting and theater at the California State University, Northridge. He is a friend of Fred Willard, Rob Paulsen, Barry Dennen and Billy West, who voiced Zim in the pilot episode. He lives with his wife, playwright and screenwriter Kristen Lazarian, and their three sons: Cole, Jake and Wyatt. The couple's oldest of their three sons, Jake Elliot Horvitz (born April 11, 1997), was mentioned in one of his event for The Angry Beavers. He and Lazarian wrote an episode of The Grim Adventures of Billy and Mandy with the episode's storyboard artist C. H. Greenblatt, "Keeper of the Reaper".

Career

Horvitz first appeared in the 1976 Freshen Up Gum commercial, which led to other commercial appearances and several hand modeling jobs. After a brief stint in an off-Broadway production of Oliver!, he went on to make appearances on TV shows such as Kids Incorporated and Safe at Home and films, such as Summer School, How I Got Into College and Deadly Weapon. He also starred as Howie for two seasons on the 1988 syndicated television sitcom The Munsters Today which lasted three years until 1991. Howie was best friend of Marilyn Munster (played by actress Hilary Van Dyke). Starting in 1993, he changed the focus of his career to voice acting, starting with voice of Alpha 5 on the live-action series Mighty Morphin' Power Rangers. This is one of Richard's often-forgotten roles that he has performed. From here, he expanded into several other particular voice roles on such animated shows as The Angry Beavers (Daggett), Invader Zim (Zim), Kim Possible, Dave the Barbarian (Ned Frischman), Zatch Bell! (Kanchomé), The Grim Adventures of Billy and Mandy (Billy, Billy's dad), Ben 10 (Grey Matter), Squirrel Boy (Rodney), and Shorty McShorts' Shorts as Dudley. After his stint as Alpha 5 ended, Horvitz went on to voice a few monsters in other Power Rangers series, and was also the voice of Alpha 7 in the Power Rangers: Wild Force episode, "Forever Red". He also played the main character Razputin in Psychonauts, and Orthopox in Destroy All Humans!, Destroy All Humans! 2 and Destroy All Humans! Path of the Furon, (not Destroy All Humans! Big Willy Unleashed) in a voice that closely resembles that of Zim (rather, what would happen if Zim adopted an English accent). He has voiced various NPCs in Everquest 2. He voiced the Berserker Darklings in The Darkness, Bumble in Kinectimals and Kaos in Skylanders: Spyro's Adventure. Horvitz also voiced "Green Grapes" in the Fruit of the Loom commercials. He has also acted on stage, including in Jeffrey Hatcher's "Mrs. Mannerly" in Boston.
