The Vampire Of Düsseldorf - 1965 - 6/10
AKA - Le Vampire de Düsseldorf

There is a serial killer prowling the streets, so the young ladies feel safe with a handsome escort.
Except, after one is safely home, he asks the other female to go to the midnight park.
Where, it turns out, he suffers deadly impulses, and carries a knife.
He is also a steady regular at the Eldorado cabaret, where the sexy Anna arouses his desire.

Based on Peter Kürten, this well captures the shaky Weimar era.
Seedy clubs, economic and political strife, casual violence from the SA.
One establishment featured numbered table phones for assignations (similar to Berlin’s Resi).
Moody cinema, with a mannered performance by Robert Hossein that may not suit all tastes.
