His claim to fame was playing Danny Torrence in "The Shining," but he made only one other film and decided not to pursue acting as an adult

Because he was so young when he acted in "The Shining," director Stanly Kubrick kept much of the disturbing content of the film hidden from him, and he didn't even know the film was a horror film until several years later
