Death Wish 4: The Crackdown (1987)

Revealing mistake: When Frank Bauggs is fighting Paul Kersey, in the shot where Frank is about to run through a window you can see that the window is cracked just before he goes through it. (00:50:40)

Jeffy

Nathan White: I know about your friend's daughter, Mr. Kersey. I also know that you shot the pusher who sold her the drugs. But I ask you, sir, what about the people behind him? How many children do we let them destroy before we say enough, Mr. Kersey? How many?

Trivia: Even though they play mother and daughter in this film, Kay Lenz (born 1953) is only thirteen years older than Dana Barron (born 1966).
