The seven films Josef von Sternberg and Marlene Dietrich made together are like intoxicating fleurs du mal : erotic, dark, witty, sublime, and modern. Together they honed Dietrich's complex, sultry and feline persona and brought a whiff of genuine Weimar decadence to mainstream Hollywood. After their personal and professional relationship imploded with The Devil is a Woman in 1935 Dietrich went on to work with major directors like Billy Wilder, Fritz Lang and Alfred Hitchcock and tour her acclaimed one-woman cabaret show around the world well into her 70s. For von Sternberg - who'd antagonised a lot of people in his 1930s heyday with his volatile tyrannical temperament - his post-Dietrich career was one long, humiliating decline.

1941's Shanghai Gesture represents one of von Sternberg's last gasps before losing creative autonomy (During the filming of 1952's Macao , he'd be sacked midway through production and replaced by Nicholas Ray). A torrid and baroque study in vengeance and corruption, the film sees Von Sternberg re-visiting the locale of Shanghai Express , his 1932 triumph with Dietrich. Sir Guy Charteris (Walter Huston), a rich white industrialist with a murky past, is seeking to gentrify Shanghai (he calls it "the cesspool of the Far East"). When gorgon-like dragon lady Mother Gin Sling (Ona Munson) learns he intends to close her gambling den she starts plotting her revenge. Meanwhile, slumming rich girl Poppy (the exquisite Gene Tierney) becomes ensnared by the toxic allure of the casino ("It smells so incredibly evil ..."), addicted both to gambling and the heavy-lidded charms of Dr Omar (a torpid Victor Mature in a burnoose and fez).

Von Sternberg was Hollywood's most seductive visual stylist. Here he evokes a sensual and depraved Shanghai of the imagination, an underworld of opium-scented exotica. Mother Gin Sling's vice palace is a glittering Art Deco inner circle of hell, where the beautiful and the damned drink cocktails of brandy and sulphur and gamble away their souls. A Chinese New Year parade is depicted as a macabre carnival; Mother Gin Sling's climactic New Year's Eve party culminates with the surreal sight of terrified female "white slaves" being hoisted skyward in cages.

The overripe, purple dialogue occasionally threatens to tip the film into kitsch (Dr Omar calls Poppy "my plucked bird of paradise").  But even in a scratchy, muffled DVD transfer, Shanghai Gesture is a hypnotic, shimmering spectacle and its treatment of miscegenation and colonialism is way ahead of its time. And as portrayed by Munson (best-remembered as bordello madam Belle Watling in Gone with the Wind ) with a purring voice, serene mask-like face and Medusa hairstyle, Mother Gin Sling is a mesmerizing villainess
