'Marilyn' aka 'Roadhouse Girl' (1953) – Wolf Rilla.

B-Movie maestro Wolf Rilla 'rilla' delivers some super-melodramatic Brit-Noir pizazz in the splendidly monikered 'Roadhouse Girl', a low-budget, high blood-pressured, doomily Dashiell Hammett-ed pot-boiler, wherein itinerant grease monkey, the tall drink of dish water Tom Price (Maxwell Reed) secures employment at an isolated, somewhat insalubrious roadside garage, owned by dour, hypertensive, oily misanthrope George Sanders (Leslie Dwyer), who is incongruously married to the breathtakingly beauteous, vastly frustrated, serially flirtatious Marilyn (Sandra Dorne), and before you can say 'lipstick on my crankshaft', the considerably 'handy' Tom enthusiastically provides some extracurricular lubrication service for this divine-looking, dingy dive-dancin' Roadhouse-rocking, B-Movie bombshell! 

Wolf Rilla's black-seamed, steamy-windowed melodrama about the increasingly volatile ménage à trois between Brylcreemed, sleazy operator Nick (Ferdy Mayne), the wildly quixotic, weirdly petulant Marilyn, and big, greasy-fingered lug Tom sinfully simmers to a suitably fraught, deliciously dramatic, exciting B-Movie Noir conclusion! In this delightfully tawdry, tannin-stained, low rent gloomy thriller, overheated, highly revved, erotically charged emotions dangerously percolate to a perfectly hysterical, wonderfully camp, bathos-laden climax, while juicy bombshell Marilyn is initially one sticky sweet confection, said glossy veneer belies a poisonously malignant centre, 'Marilyn' is moody Brit-Noir at its finest/dingiest!
