Trivia: Screenwriter Aaron Sorkin has a cameo as a lawyer in a bar talking to a woman about one of his cases.
Trivia: A Few Good Men was based loosely on an incident which involved a group of soldiers performing a hazing act on a recruit by the order of their platoon commander. The recruit nearly died, and it wasn't until the commander finally confessed in court that the soldiers were let off. This is confirmed by the director commentary.
Trivia: The marching band in the beginning is The Capital Band and has a brief mention in the closing credits. The director in black is Col Charles Erwin, USMC Ret, former Assistant Conductor and solo cornet for the President's Marine band. The Marine Corps would not allow the real band to be shown in the film. Col Erwin used his Capital Band for the scene.
Trivia: This movie, which was adapted from the play, was actually based on a real-life Code Red event. In Guantanamo Bay, Lance Corporal David Cox and nine other men tied up and severely beat a Marine for snitching to the NCIS. Cox was found not guilty, although he was sentenced to thirty days for simple assault and honorably discharged. In 1994, Cox disappeared but was found three months later murdered, execution style.
