There’s a longer video (26 min.) at ComicBookMovie – scroll down about half way – about all the stunt work and the preparation for the fight sequences in the film; the short video we saw earlier is taken from this longer version. We can’t embed it here, so click on the link and watch it there. Russell’s part starts about 12 min. in, and goes on past the end of the shorter vid; and then again at about 15 min, there is a small part about his fighting skills and shows the motion capture work he and Shannon did for their sequence.
We’ve taken a few screen captures, just because. Click for larger version.
