"The Canterville Ghost" is a 1986 film adaptation of the short story by Oscar Wilde. The story follows an American family, the Otises, who move into a haunted English mansion, Canterville Chase. They encounter the ghost, Sir Simon, who has been haunting the estate for centuries.

Instead of being frightened, they challenge him, leading to humorous situations. The film explores themes of family, friendship, and the clash of cultures between America and England.
