John Blyth Barrymore III (born May 15, 1954) is an American former film and television actor.
He is known for his role as Zeke in the 1970s television series Kung Fu, which was his first role on television.
John Blyth Barrymore III was born to John Drew Barrymore and Cara Williams. As such, he is from the famous Barrymore family: He is the half-brother of American actress Drew Barrymore, as well as the grandnephew of Ethel Barrymore and Lionel Barrymore. He is of partial Irish descent through his great-grandfather, actor Maurice Costello. John has stated that he does not remember if he has met his aunt Diana Barrymore, also an actress.
Norman Abbott, the director of the television show The Munsters, requested that John play the role of Eddie Munster in the show. John's mother did not allow him to take the role, and in later years John thanked his mother for not allowing him to become a child actor.
After a paltry career in film and television, John found himself homeless in 2012, though he was able to get a food stamps card. While on skid row, he took to wearing a shirt printed with "I'm Drew Barrymore's brother".
