The Black Torment (a.k.a. Estate of Insanity) is a 1964 British gothic horror film directed by Robert Hartford-Davis and starring John Turner, Heather Sears and Ann Lynn. The film is set in 18th-century Devon and was scripted by brothers Donald and Derek Ford. In terms of plot and setting it shares many similarities with the Hammer Horror productions of the 1960s, but was made by a smaller studio, Compton Films (see Tony Tenser). The Ford brothers later scripted Corruption (1968), also directed by Robert Hartford-Davis.
