Trivia: The archery coach for the film was the famous master bowman Howard Hill (he successfully hunted an elephant with a longbow). He also performed the "trick" shots, and appears in the movie as the black-bearded archer Robin defeats in the "finals" of the archery contest.
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: Sol Gorss who was the stuntman who plays the fourth guard to get shot with an arrow during the first fight was actually the first stuntman to be shot by Howard Hill. This was the first time Howard Hill had shot a real human target, and even with the extra padding under Gorss' costume they weren't 100 percent sure how it would turn out.
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.
