Daughter of Dr. Jekyll. (1957) – Edgar G. Ulmer.

'After you've had a nice sleep, you'll feel like another girl!!!'

The maestro of The Black Cat and Detour presents his winning slice of 50s faux gothic terror, providing yet another, albeit alternative misadventure of Stevenson's immortally mutable monster. Beautiful bride-to-be (Gloria Talbott), and her butch beau (John Agar) return to her stately ancestral abode, discovering that one hidden room reveals a most terrible secret pertaining to the fate of Dr Jekyll's Daughter! John Agar was the Tyrone Power of vintage B's, handsome, charismatic, and physically robust, his steely presence often providing the rigid backbone that needfully bolstered the increasingly schlocky scenarios. Bit of a curate's egg, while the atmospheric exterior shots prove lively and expressive, the interiors are mostly leaden, flatly lit, being stolidly suggestive of a fusty TV melodrama. Not always compelling, yet Daughter of Dr. Jekyll's diffused, theremin-enriched scenes of nocturnal monster-mashing remain piquant. Studly John Agar is at his pristine good-guy best, and the lovely Ms. Talbott is surprisingly nuanced as the greatly Gaslit Jekyll heiress.
