It was probably a TV movie. It was black and white, probably 1940smth-1960smth. It was about a family who lived in a haunted house on some kind of hill by the sea. The house was haunted by three ghosts - maid, butler and female owner - they were in love triangle: the owner was in love in butler, he was in love with the maid, so the owner killed the maid, I suppose butler tried to stop it or killed himself... something like that. The ghost weren't evil, they were fighting with each other, like they were still alive, like they were reliving their life once more. I remember some scenes of ateir argue in the kitchen...
I remember there was a really fat uncle in that family who fell down the hill and died. I remember him walking with one of the ghosts.
I remember also there was some scene at cemetary - a young boy tried to find out who were the ghosts from local friend.
It seems like forever to find this movie... and it is not a "Haunted house on the hill" It wasn't a scary movie, rather funny, a little romantic (?).
