Stumbled on this from one of the attendees at a recent convention where Arrow’s Stephen Amell was doing a Q&A. Apparently James directed the final fight scene on the Arrow Season 2 finale.
Stephen Amell at Eek! Comic and Pop Culture Fest:
“Q: How long does it take to choreograph a fight scene?
A: About two weeks. James Bamford is the fight director. They do rough video with non-actors, actors then follow the choreography. When the last fight of the finale was filmed, Bamford basically had directorial control of the set.”
