The Courtship of Eddie's Father (1963)

Realizing that he needs a mother -- and his widower father, Tom (Glenn Ford), needs a wife -- precocious Eddie Corbett (Ron Howard) is determined to get his dad remarried. While Tom dates numerous women, including the uptight aristocrat Rita Behrens (Dina Merrill), nobody seems to be a good fit for Eddie or his father. Soon it becomes apparent that Tom's ideal match may be closer than he thought, as he begins to develop feelings for his lovely neighbor, Elizabeth Marten (Shirley Jones).
