Deliberate mistake: The extras used in the scene when Danny gets assigned the case appear again as members of the jury. If Danny's colleagues were called as jury members for a trial all would have to declare a conflict of interest and be ineligible to hear the case. (00:09:30 - 01:03:25)

Continuity mistake: During the trial at the end, Jessup struggles with the MPs to get to Danny Kaffee. After the struggle, his tie is all out of place. In the following close-up shots, it's re-aligned, before becoming completely askew as Jessup goes to retrieve his hat.
Col. Nathan R. Jessup: Sweet dreams, son.
Lt. Daniel Kaffee: Don't call me son. I am a lawyer and officer in the United States Navy, and you're under arrest, you son of a bitch.
Trivia: Screenwriter Aaron Sorkin has a cameo as a lawyer in a bar talking to a woman about one of his cases.
Question: While questioning the doctor on the witness stand, Kaffee asks him if a heart condition could have caused the fatal lactic acidosis rather than a mysterious poison on the rag stuffed in his mouth. Under the circumstances of the Marine's death, wouldn't a complete autopsy have been performed to positively determine the cause of death? And if an autopsy were performed, wouldn't the heart condition have easily been discovered?
Answer: An autopsy can show what physically caused a death, but not necessarily what led up to it. Kaffee is trying to prove that there could be more than one reason for the marine's death.
