I'll step in for a minute with another view.
It seems to me that many, if not most, of the recent movies that use physical fights with swords and other styles of fighting depend heavily on camera editing and short sequences of two to three moves assembled together to build a complete fight. If you've seen the second Frazer Mummy movie with the two gals doing the "Egyptian" fight, you may have noticed the two stars doing very short takes that involved brief sequential moves before cutting to another camera angle or viewpoint.
The same style was used in Chicago for most of the dance scenes with the stars, particularly Zeta-Jones.
Is that for dramatic effect, to be trendy, to spice up the action, to add zip, or is it because the actors involved are less able to maintain the flow of longer sequences?
Contrast the classic (admittedly "stage" fighting) sword fights in Mark Of Zorro between Basil Rathbone (an accomplished fencer) & Tyrone Power, and in Robin Hood between Rathbone and Errol Flynn. Also, the more recent Princess Bride between Elwes and Patinkin. Stunt doubles, i.e. sword coaches, were used here & there in all three movies, but there are sequences where the choreography is well done, the stars themselves are obviously doing the bladework, and the action continues for much longer before the camera cuts to another view.
If you can "master" six moves between "Action!" and "Cut", then master six more moves, then six more, you can probably put on a pretty good show when the film is all spliced together on a master negative.
I contrast Zeta-Jones with Cyd Charisse and Ginger Rogers (slightly different dance styles, yes), among others. Older dancers could sustain longer sequences without interruptions and editing, it seems.
Could be wrong, but I think today in sword fights it's more camera and editing than individual skill.
I can still watch the older Zorro and Robin Hood and still admire those sword fights, even though I've seen them both at least 20 times.
I can't do that with the Egyptian Mummy fight, it's too frenetic & jumps around too much. I can't even watch Chicago all the way through, hard on my eyes, the camera never holds still during the dance scenes.
What do you think?
