Actually if we are talking purely about sword fighting skills, then except for Maul, I'm really not impressed with any of the other fighters shown in the SW movies, either the OT or the prequels. I mean, none of the actors in the movies, i.e. Alec Guiness, or David Prowse, or Mark Hamill, Liam Neeson, Ewan Mcgregor, Hayden .... none of them are really sword fighters ... Alec Guiness and David Prowse especially. So most of those lightsabre fights, for me, have a kinda cosmetic look to them.
Except for Darth Maul. Because Ray Parks IS in fact i genuine martiall artist, and he looks like a real fighter using those swords.
I'm not talking about the characters here ... but of all the actors, Ray Parks is definitely the best fighter ... he's no actor, but he's a genuine fighter. He'd beat any of the other actors in a real fight. Which is why, I divorce the characters from the actors playing them. I mean ... Count Dooku would beat Darth Maul in a lightsabre duel. I just ignore the fact, that on screen, it's a bit of the stretch of the imagination to see that, cause Cristopher Lee wouldn't stand a chance against Ray Park in real life.
Artistic license, I guess.
Well u know, if on screen, they hypothetically showed Dooku beating Maul ( because Dooku IS a stronger jedi than Maul ), that would be right of course ... the way they've been characterized Count Dooku, although an old man, is stronger than Darth Maul.
However, that would again create, in my mind, a tinge of unreality ... cause Ray Parks, is obviously stronger and faster and more powerful than Cristopher Lee, who, though trained in fencing, is NOT a combat fighter or a martial artist, which Ray Parks is .. and no matter how the fight director would try to cleverly disguise that, it would still definitely come out to a certain extent.
I know I'm not supposed to see Ray Parks or Cristopher Lee ... but if they were ever shown on screen in a lightsabre duel, no matter how cleverly they covered it up, at some point it would be clearly to me as a viewer, that Ray Parks is a stronger and faster man than Cristopher Lee ... so although I would not be looking at Parks and Lee, but at Maul and Dooku .... it would apppear as if ... Maul is stronger and faster than Dooku ... but that of course is not true ... cause Dooku is the stronger sith ... that's where the artistic license thing comes in ... I would just ignore that part of it I guess.
