A six-time Emmy Award winner, this daily animated series, based on Marc Brown's best-selling Arthur adventure books, shows how Arthur and his friends use effective, age-appropriate problem-solving skills. In Season 13, the series once again takes on a difficult topic that impacts kids and their parents in a profound way — cancer. Lance Armstrong returns to Elwood City for the two-part episode "The Great MacGrady," about an illness that affects the lives of so many children. Also in Season 13, Academy Award-winning actor Philip Seymour Hoffman lends his voice as director Will Toffman in "No Acting Please," a unique premiere episode about theater and the joy of the performing arts.
