After selling the movie rights, Adleman and his wife moved from Philadelphia to Malibu, California. They remained there for a number of years until they acquired a large ranch property in Oregon. At which point they opened the restaurant The Bella Union, featuring the "peach baboo", a cocktail named after their grandson's childhood treat. Adleman died in Ashland, Oregon, in 1995. His wife and two daughters scattered his ashes on the ocean at the beach in Malibu.
