Shortly after Brothers ended its run, Maggart appeared as Lynn Redgrave's brother on the short-lived, and much talked about Jackie Mason sitcom Chicken Soup. In 1990, he had a notable guest turn on the Fox sitcom Babes, playing the ex-husband of Susan Peretz's character, Darlene Gilbert. Since that time, Maggart has devoted much of his time to painting and writing. His paintings have been featured on The Venice Art Walk. His poem Diversity in Venice was read at The Venice Centennial in 2005. His first book is an autobiographical trilogy/memoir called Papa's Footprint. It tells the tale of a four-million-year-old actor and father, from Africa to Broadway and Hollywood.
