See double with Hammer Horror classic Twins of Evil, in a 4K restoration by Imprint Films. They look alike. They dress alike. Two identical beauties... but one of them has the very devil in her. Starring the great Peter Cushing alongside real-life identical twins Madeleine and Mary Collinson, this steamy, daring vampire film is based on the 1872 novella Carmilla by Sheridan Le Fanu.
