According to the video, Amell and Nable performed their own shirtless stunt work on location on Grouse Mountain. "Arrow" fight designer James Bamford, who narrates the clip, offers some insight on the differences between the characters' fighting styles as well as a few shots of his crew coordinating the scene.
Check out the video below to learn more about the work that went into "Arrow's" mid-season finale.
And for those "Arrow" fans who just can't get enough of Nable's turn as Ra's al Ghul, after seeing him hanging out in the Lazarus Pit on this week's episode the CBR crew imagined him starring in a very different series via our Twitter and Facebook. You're welcome.
"Arrow" airs Wednesdays at 8 p.m. EST on the CW.
