Beyond acting, Mull wrote parody songs, performed with legends like Frank Zappa, and co-created the satirical The History of White People in America. His humor, often quirky and jazz-infused, set him apart.
A Rhode Island School of Design alum, Mull never lost his love for painting or making people laugh. His passing leaves behind a legacy of laughs, art, and heart. He is survived by his wife, Wendy Haas, and daughter, Maggie.
