 But then again... In the famous "snapping" swordfight between Kaye  and Rathbone, Kayes sword movements were too fast for Rathbone, as  he was 63 at the time of filming. The films fight choreographer  dressed up as Rathbones character and was filmed from behind for  the fast sections. If you look, you can see that most of the fight  consists of "Rathbone" from the back, then shots of the real  Rathbone standing "en garde".
