Dracula: Prince of Darkness (1966, dir. Terence Fisher)

English tourists find themselves at a remote Carpathian castle against locals’ advice. Brisk direct sequel to Hammer’s 1958 Dracula, without Cushing this time, but instead using bits of the Stoker (like the Renfield subplot) not co-opted first time. Some effective direction and visual imagery, plus sly humour from Philip Latham as manservant Klove.

Here’s the trailer.
