 "Alraune (1952)" is the fifth adaptation of Ewer's book, the first being the 1918 silent version directed by Michael Curtiz which has long been believed to no longer exist in studio archives.The second adaptation came shortly after which, despite the title, has very little to no connection to the novel other than the Mandrake root.A third adaptation was then released a decade later with Alraune (1928 film), a black and white version though silent, with it being widely considered the best adaptation which was directed by Henrik Galeen.
