Do you have any more details about the film? About when it was made? Was it set in a definable time period? Any stars in it that you remember?
I do think it was a 40s or 50s film. I always thought it was Cary Grant, but a perusal of his work shows that it isnt him. It was a manly suited man like Grant and a well known woman for the mother. Cannot remember the young girl much.
