Designed more for train-wreck gawkery than psychological illumination, Tom Kalin’s garish melodrama applies icehouse style to hothouse material: the 1972 murder of socialite Barbara Daly Baekeland, former wife of the heir to the Bakelite fortune, by the grown son she’d taken to fucking to cure his homosexuality. From the life-preserver-clinging of his culture-vulture mom (Julianne Moore) to the contempt of his aloof playboy dad (Stephen Dillane), young Antony Baekeland was molded from birth into a sexually confused, neurotic mama’s boy (played as an adult by Eddie Redmayne). His standing as his mother’s de facto husband led inevitably to incest, violence, and a grimly redundant self-suffocation; in Kalin and screenwriter Howard A. Rodman’s hands, his downfall becomes a glossy travelogue with stops in Paris, Majorca, and London (where a fateful kitchen knife awaits). This marks Kalin’s first feature in the 15 years since his queer-cinema landmark Swoon, a grave, provocative retelling of the Leopold and Loeb case. This, by contrast, is a tawdry nighttime soap that marvels without insight at its characters’ despicable behavior: It squanders a major performance by Moore, who rips into Barbara’s confrontational mania, maternal perversity, and all-consuming need with nail-clawing fury and no small amount of malicious humor—as when she tries to quiet her increasingly agitated son/hand-job recipient with a sharp “Inside voice!”
