Guess Who's Coming to Dinner (1967)

Continuity mistake: 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.

Revealing mistake: When Spencer Tracey backs his car into the hotrod at the ice cream stand, you can see the hotrod already has a sizable dent before the car makes contact, probably a result of a previous take.

Continuity mistake: Towards the end of the film when Spencer Tracy and Katharine Hepburn are in their bathroom talking, Spencer is in the process of shaving. At one point, you see his face covered with shaving cream. When it cuts to Katherine and then back to him, the shaving cream is spread differently on his face. When it cuts to her again and back, it is different again.

Trivia: The daughter was played by Katharine Hepburn's real life niece, Katharine Houghton.

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.

Trivia: The movie makers got Poiter to sign on after telling him that Spencer and Katharine were going to be in the film. They in fact had not signed on at that point.

Tillie: All hell done broke loose now.

Joanna Drayton: It never occurred to me that I would fall in love with a Negro, but I have, and nothing's going to change that.

Matt Drayton: When I had ice cream before, I had a special kind of flavor that I liked very much but I can't remember what it was.
Carhop: I'll bring you the list, sir.
Matt Drayton: Oh no. You - you must know what it is.
Carhop: Daquiri Ice, Honeycomb Candy, Cocoa, Coconut, Jamocha Almond Fudge, Mocha Jamocha, Peanut Butter and Jelly, Cinnamon, Banana Mint.
Matt Drayton: Must've been some other place.
