The English upper class are notoriously barmy, and it is surprising that they have not featured more as villains in the realms of B-movie horror. Italian schlock masterpiece The Night Evelyn Came Out of the Grave has a rather whacky upper class killer in the form of Lord Alan Cunningham (played by Anthony Steffen), a man obsessed with the fidelity of his dead wife, which leads to murderous results.
For fans of Euro-Horror, this film has everything in it - murder, madness, torture, seances, and sex, and is a psychedelic slasher, in need of more drugs not less. One for Halloween - if you can find the uncut version.
