I don't know who starred in the film, but basically it is a old black and white, the guy was married and his wife died and her ghost sits on the bridge at the end of the road. The guy remarries and his dead wife haunts the new one. In the end both wives die and sit on the bridge and plot how to kill their husband, they tamper with the brakes on his car and he crashes into the bridge and there they all sit Dead and Together.
Can anyone help because I really liked this film but have no idea what its called

Thanks
