Where to watch Boom! (1968)

Secluding herself in an island mansion in the Mediterranean with her servants and nurses, the wealthy Flora "Sissy" Goforth prepares for her impending death -- and she isn't the only one who's waiting. Known for his attraction to the dying rich, poet Chris Flanders ingratiates himself with the wilting Sissy. Although her friend explains Flanders' "Angel of Death" nature to her, Sissy embraces the vulture-like Flanders.
