As Barrymore became more and more reclusive, he withdrew from acting, with his final two appearances being a 1974 episode of "Kung Fu" and an uncredited role in the 1976 film "Baby Blue Marine". Barrymore suffered from the same addiction problems that had destroyed his father. Although he continued to appear occasionally onscreen, he became more and more reclusive, eventually disappearing into the wilderness to live a mystical existence that has also been described as derelict. He was estranged from his family, including his children, and his lifestyle continued to worsen as his physical and mental health deteriorated.
