Overview
The Oblong Box is a 1969 British gothic horror film directed by Gordon Hessler, starring Vincent Price, Christopher Lee and Alister Williamson. This was the first film to star both Price and Lee.
Taking its title from the 1844 short story "The Oblong Box", it explores and combines several themes typical to the work of Edgar Allan Poe, such as premature burial and masked figures, with the non-Poe theme of voodoo ritual killings.
Plot
The film takes place in England in 1865. Having been grotesquely disfigured in an African voodoo ceremony for a transgression against the native populace, Sir Edward Markham (Alister Williamson) is kept locked in his room by his guilt-ridden brother, Julian (Vincent Price).
