In addition to her on-screen roles, Murphy was an accomplished voice actress who worked in films like “Happy Feet” and “Futurama: The Beast with a Billion Backs,” as well as video games. But it was on television where Murphy started doing voice work, acting in more than 250 episodes of FOX’s popular “King of the Hill” during the show’s 13-year run. While she voiced a variety of side characters and teenager Joseph Gribble (for the first four seasons), her main gig was Hank Hill’s dimwitted niece, Luanne Platter. It would go on to become one of her most career-defining parts.
“King of the Hill” was on the air from 1997 to 2010, which makes it one of the longest-running cartoons in history (per IMDB). Murphy was recognized for her voice work with Annie Award nominations in 1997, 2000, and 2004, finally winning on her final nod. “Brittany Murphy was like no other,” said Kathy Najimy, who voiced Peggy Hill on the show, upon Murphy’s passing. “A bright light. Never a mean or judgmental word, wildly fun, silly, loyal friend. Sweet, funny, smart, unbelievably talented actress and singer [with a] brilliant, moving body of work.”
