Once in a while I come on here and ask the same question...
I have a really strong and lovely memory of watching this film when I was a kid with my mum. It was black and white and looked a bit like abbot and costello style screwball comedy.
A family moved into a house, it was haunted by a ghost or several ghosts.
The ending saw the family drive off down the road after selling the house, unbeknownst to them, the ghosts were all sitting on the back of their old fashioned car (1930s style car with no roof and a suitcase on the back) they were facing away from the driver and looking at the camera , Then 'The End' in swirly writing came on.
It looked to be similar vintage to Abbot and Costello. I would have been watching this in about 1984 and it was old then.
It definitely isn't The Ghost and Mrs Muir. I have seen that and know it well.
I'd love to find it. Anyone recognise it?
