Count Dracula's three sisters, also vampires, sleep in coffins in the dungeons of Castle Dracula.
Dracula, 1931. Bela Lugosi as the vampire is not a figure in masquerade but a fiend who actually sucks the blood of humans, in this case Helen Chandler’s.
The Return of the Vampire, 1944. The Wolf Man, Matt Willis, tenderly opens the coffin bed of the vampire, Bela Lugosi, apparently for the purpose of delivering a package.
