Returning to the set, Martin began shooting the major action scenes, which were mostly gunfight sequences.
His long-term shooting practice paid off as he handled several types of handguns with great proficiency, just like a professional marksman.
For the more challenging stunts, Buck and Lewis, the stunt actors, took turns stepping in.
They had worked with Martin on The Hills Have Eyes Crew and had similar builds.
Action director Chad personally took part, filming knife-fighting and close-quarters combat scenes with Martin.
After a fight scene was finished, Martin had just returned to the rest area when Chris Pratt came over with a towel.
Handing it to Martin, he said, "You're really multitalented, great with guns and knives."
Martin could tell he was being flattered and took the towel to wipe off sweat before asking, "I heard you're pretty good at dancing?"
