How should I do this for my next scene shoot?

My next and hopefully my last scene shoot for my film. I want finish a fight/chase scene I already shot most of. I need the actors to dub their lines, during the fight, which I couldn't get the mic, in cause the camera was panning around. How do I get the actors in their mood, to get the lines, grunts, and screams to come off correct for the fight? Should I sit them down and have them do it, or would it be much better, if I had them actually do parts of the fight, with no camera, and just recorded sound with the mic close to their mouths, to make it sound more real?


The other problem I mentioned before is that it goes from room to room, and I forgot to switch the white balance as the rooms switched lights, going from one to the other for the last few shots. So I can do two things. Either keep the original shots, which will have to be switched back and loose color saturation, or reshoot all that I got wrong.

I would like to keep the originals I already have, as the actors worked very hard, and it would be hard to push them to do some of the stunts over. I was hoping to keep those stunts, and do the new shots, with the correct white balances, then cut back and forth between the slightly desaturated shots, and the new non desaturated. But would audiences find that watchable, or would it be too bothersome? I don't want to have to desaturate the whole thing, and would rather reshoot, if I can't get it all to match, without desaturation. Thanks for the replies.
 
You would probably make an adjustment layer with a mask to target just that side of the frame and use color finesse or levels to play with the lighting of the scene... copying and pasting light is difficult as there's generally enough variation within even a small part of your frame to make it not match well.

This coupled with matting tutorials on VC and maybe some others that you can seek out by using terms such as "luma matte" and "rotoscoping" on youtube can be combined to suit your footage and help you dial in the correction you're going for.
 
The wall is a flat rectangle... put a box around it... the human shape is a more complex thing... roto that separately, in chunks (the torso doesn't change shape, nor do the parts of the arms or the head) that are unbending shapes... break it down. Then use the main rectangle as the matte, but exclude the other roto's from that matte. One piece at a time makes the job go much more quickly than trying to manage all of those roto points on the shape on a per frame basis... this way, you can just move each of the shapes and they'll tend to consist of many fewer points over all and even fewer that change relationship drastically.
