I think the film Is Endless night, by Agatha Christie....
Michael Rogers is a chauffeur with little money, but big dreams. Foremost of these is building his dream house on the perfect piece of land. Michael gets his chance when his new girlfriend, Ellie, turns out to be an extremely wealthy heiress. The two are wed and are soon living in a modern home on Gipsy's Acre. Their idyllic life shatters around them with a series of bizarre events and threats. Micheal comes under the disapproving eye of both Ellie's greedy family and her interfering best-friend Greta. On top of that, local legend says their property is cursed. What danger lurks for the young newlyweds, and is it a human plot or something supernatural?
