Trivia: Listen carefully to the sounds the swords make during the final battle at Nottingham castle. When Robin and Sir Guy are fighting, they sound different (clanging as opposed to clicking) than all the other combatants. The reason for the discrepancy is simple. Errol Flynn and Basil Rathbone, both experienced performers, are using real steel swords for their one-on-one fight scenes, while everyone else is using plastic props.
Trivia: Stuntmen were paid $150 to get shot with real arrows shot by Howard Hill. They wore metal plates covered in cork to stop the arrows under their clothes.
