Family Plot (1976)

Continuity mistake: In the scene where Bruce Dern and Barbara Harris are eating hamburgers. He has two on his plate, from a back view she reaches over and takes one. He then removes the cap from the ketchup bottle. The shot switches to a view from his back and the cap is back on the ketchup. He then removes the cap again.

Continuity mistake: Harris' white Mustang is parked so as to block the exit from the bad guys' garage, but in a later scene it is moved so that it is only partly blocking the garage.

Trivia: Alfred Hitchcock's silhouette can be seen in the window of the registry of births and deaths office. He is the figure on the right pointing at the figure on the left.
