Continuity mistake: In the scene where Jo is telling Danny that she sent one of the prisoners some comic books (towards the beginning of the movie)he steps inside his car and the back window is halfway down. As he drives away it is completely up and as he pulls into the next scene, it is still up, while his driver side window remains down the whole time.
Continuity mistake: When Jack Ross (Kevin Bacon) calls his first witness to the stand, he steps over to the podium between himself and the defense counsel, but in the wide shot showing the witness walking across the courtroom, he is back at his table. Then in the following close-up he is once again at the podium.
Continuity mistake: During Danny's examination of Lt. Kendrick on the witness stand, he leans up against his courtroom table, shot from the back, in front of the microphone which is straight on, on the table. The next shot, from the front, shows the mic to the left of him and on an angle.
Continuity mistake: After Danny tells Jessep to sit back down on the witness stand and the judge is telling Danny how to address Jessep, he pours himself a glass of water. From the shot where his back is towards us he puts the pitcher down. We then see a shot in front of him and he is putting the pitcher down again.
Continuity mistake: When Danny asks for his bat and Jo (Demi Moore)says she put it in the closet, her elbows are on the table with her hands clasped. She then breaks them and puts the right one on the table. The next shot shows her and Danny and her elbows are on the table again with her hand clasped.
Continuity mistake: When Joanne comes to ask Danny why he has not yet seen his clients, he is just about to swing the bat, and begins to as the shot switches to her face. However, in the very next shot he's standing with the bat, waiting to swing again. The time between the two shots would not have provided adequate time for him to swing and then be waiting for another throw.
Continuity mistake: When Kaffee drives up to the newsstand at night and buys his magazine and chats with the news vendor, his tie knot is undone down to the second button on his shirt. When he returns to his car and is startled by Markinson in the back seat, his tie is undone only a bit past the first button, much higher than the previous shot. This is largely due, Director Rob Reiner explains, to the fact that part of the scene was shot in D.C. and part of the scene was shot in L.A.
