Haunted.
I think this film was set in the Edwardian period. I last saw it in 1999 when it was screened on British TV (not sure which channel).
A chap is invited to stay at a country house for the weekend. He meets a beautiful young woman, her brother and some other people also staying at the house. He later discovers that they are all ghosts and the house had been burnt down some years earlier.
Haunted based on the novel by James Herbert.
