Jimmy Sangster's script for Horror of Dracula (the first of Hammer's popular vampire series) plays it fast and loose with Stoker's classic novel in almost every department, changing the nature of Jonathan Harker's visit to Castle Dracula, omitting the bloodsucker's overseas excursion to Whitby entirely, and even doing away with my favourite character from the book, bug-eating loon Renfield.
Despite this radical reworking of the source material, the film is still a highly enjoyable slice of Gothic horror, one that I found a far more satisfying movie overall than Tod Browning's 1931 version, which I felt suffered from stagy direction and a somewhat hammy central performance from Lugosi.
With director Terence Fisher's understanding of the medium of film and his cast's greater experience in front of a camera, Horror of Dracula flows much more smoothly and delivers sumptuous sets, rich colour photography, and bags of creepy atmosphere into the bargain. The film is also notable for pushing the boundaries for what was acceptable in terms of sexuality and bloodletting in UK horror, establishing the winning formula for much of Hammer's output in decades to come.
7.5 out of 10, rounded up to 8 for IMDb.
