Finder of things, Doer of stuff
Another lady/gentleman mentioned that it appears as though Caviezel was merely supporting the sword in the air, and not a fighting stance. Unfortunately it will always be like that. He did not at anytime look comfortable holding his sword in his hand. I will say it for Jack Huston, and the others they looked more "natural/at home" holding their weapons.
Cool, were you an extra on set? or one of the crew?
We'll have to wait and see how it looks on film. The angle of the shots and editing can change the way stuff looks on screen considerably.
It seems a little odd that he would be uncomfortable with swords when he had to do a bunch of swordfighting in 'Count of Monte Cristo." However, fencing foils are handled quite differently than the sword in the poster so maybe that's were some of the unease comes from.
