"The Canterville Chase" is a 1985 film adaptation of the short story "The Canterville Ghost" by Oscar Wilde. The story revolves around an American family, the Otises, who move into a haunted English mansion, Canterville Chase. They encounter the ghost of Sir Simon, who has been haunting the estate for centuries. The film combines elements of comedy and fantasy as the Otis family, particularly the children, interact with Sir Simon in humorous ways. The ghost, initially frightening, becomes more of a comedic character as he tries to scare the family but ultimately finds friendship and acceptance.
