Flora 'Sissy' Goforth is a terminally ill woman living with a coterie of servants in a large mansion on a secluded island. Into her life comes a mysterious man, Christopher Flanders, nicknamed "Angelo Del Morte". The mysterious man may or may not be "The Angel of Death". The interaction between Goforth and Flanders forms the backbone of the plot, with both of the major characters voicing lines of dialogue that carry allegorical and Symbolist significance. Secondary characters chime in, such as "the Witch of Capri". The movie mingles respect and contempt for human beings who, like Goforth, continue to deny their own death even as it draws closer and closer. It examines how these characters can enlist and redirect their fading erotic drive into the reinforcement of this denial.
Filming took place on the island of Sardinia at the Porto Conte Natural Park near Alghero, and was the site of a close call for actress Taylor. A trailer that served as her dressing room came loose from its moorings only a few seconds after she stepped out of it, and "plunged over a 150-foot embankment into the sea".
Reception
The film was received poorly by critics, and maintains a 20% rating at Rotten Tomatoes from 15 reviews. Time wrote "They display the self-indulgent fecklessness of a couple of rich amateurs hamming it up at the country-club." Paul D. Zimmerman, writing for Newsweek, called it "a pompous, pointless nightmare". The Hollywood Reporter called it "An ordeal in tedium", and Saturday Review called it "Outright junk". Lawrence Devine in the Los Angeles Herald Examiner asked "Why was Boom! filmed in the first place?" Wilfred Sheed wrote in Esquire: "Let them by all means do their thing, but why film it and charge admission?" Richard Schickel wrote in Life: "That title could not be more apt; it is precisely the sound ofa bombexploding." Filmmaker John Waters admires the film, and chose it as a favorite to present in the first Maryland Film Festivalin 1999. The film's poster is visible in Waters' 1972 filmPink Flamingos. In an interview with Robert K. Elder for his book The Best Film You've Never Seen, Waters describes the film as "beyond bad. It's the other side of camp. It's beautiful, atrocious, and it's perfect. It's a perfect movie, really, and I never tire of it."
