Trivia: There is a scene in the Drayton home where Joey tells John that the tiny statue of her Father that he is holding, was made by her mother. That statue is indeed of Spencer Tracy and was actually made and given to him by Katharine Hepburn.
When Spencer Tracy backs into the blue hotrod, the cars end up kind of sideways. In the next shot it shows the cars at a 90 degree angle touching. Then in the next shot it shows them sideways again as he pulls away.
