Born in Los Angeles, California, Robert Clotworthy's introduction to voice acting came as a teenager, when he would accompany his father, a radio commercial producer, to recording sessions. There, he met legendary figures like Mel Blanc and June Foray, whose versatile talents would inspire him to pursue his own career in voice acting. Clotworthy also worked as an on-screen actor, landing minor roles in numerous episodic television series throughout the 1970s and early 1980s. By the end of the latter decade, he was working steadily on the small screen, where he enjoyed recurring roles on series like "Hunter" (NBC, 1984-1991) and "The Young and the Restless" (CBS, 1973-), as well as bit roles in features like "For the Boys" (1991). By the early '90s, however, he had segued largely into voice acting and dubbing, also known as automated dialogue replacement or ADR, for features like "The River Wild" (1994) and "American Beauty" (1999). In 1998, he was tapped to provide the voice for Jim Raynor, a major protagonist in Blizzard Entertainment's real-time strategy video game series "StarCraft." The popularity of the series led to major positive reviews from the gaming industry for Clotworthy and more high-profile voice work for "The New Batman Adventures" (The WB, 1997-99), among other projects. By the midpoint of the 2000s, Clotworthy was one of the most prolific voice actors in the industry, lending his talents to a wealth of animated projects, video games like "Kingdom Hearts II" (Square Enix, 2005) and dozens of radio and television advertisements. He was also the narrator for "Empire of Dreams: The Story of the Star Wars Trilogy," which led to additional work for Lucasfilm projects, including "Star Wars: The Legacy Revealed" (The History Channel, 2007) and "Indiana Jones: The Ultimate Quest" (2008). In 2010, he reprised his role as Jim Raynor in "StarCraft II: Wings of Liberty" (Blizzard Entertainment) while enjoying regular work as both an on-camera and voice actor for Chuck Lorre's "Two and a Half Men" (CBS, 2003-15) and "The Big Bang Theory" (CBS, 2007-).
