In 1806, the French Lieutenant Andre Duvalier (Jack Nicholson) is lost from his regiment and riding near the coast very thirsty. Out of the blue, he sees a gorgeous woman that shows him a spring. Then she tells her name, Helene (Sandra Knight), and she walks with him and vanishes into the sea water. Andre tries to save her but is attacked by an eagle and faints. He awakes in the house of and old woman, Katrina (Dorothy Neumann), and sees the eagle that belongs to her. He learns that her servant Gustaf (Jonathan Haze) has saved him. When Andre asks for Helene, Katrina tells that she does not know her. Andre walks during the night seeking out Helene; when he meets her, she asks him to follow her and brings him to a spot with quick sand, but Andre is saved by Gustaf again. He tells to Andre that Helene is possessed and he would find the answers at the castle of the Baron Victor Frederick Von Leppe (Boris Karloff) where he should ask for Eric. On the next day, Andre leaves Katrina's house and heads to the castle. He is received by the Baron himself and sees the picture of Helene on the wall. However he leans that the woman is Ilsa, the Baroness Von Leppe, who has been dead for twenty years. Further, the Baron lives alone in the castle with his butler Stefan (Richard Miller). Later he learns that the Baron found Ilsa in the bed with a man named Eric and he killed her and Stephan killed Eric. But Andre saw the woman at the window when he arrived at the castle. What is the secret of Helene?
"The Terror" is an entertaining low-budget movie by Roger Corman with Jack Nicholson and Boris Karloff. The plot is interesting and it is curious to know that Corman used sets left over from "The Raven". Boris Karloff's scenes were shot in three days only. Unfortunately the Brazilian DVD has a blurred image and it is very difficult to distinguish the characters and locations. My vote is seven.
Title (Brazil): "Sombras do Terror" ("Shadows of the Terror")
