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 met his aunt
Diana Barrymore, who was also an actress. Like his father, John has had a sporadic career in film and television, mainly appearing in shock horror movies and comedies. After John and Drew's half-sister Jessica Barrymore was found dead in her vehicle in 2014, he publicly criticized Drew for not being receptive to forming a relationship with either him or Jessica. == Filmography ==
