Of course, Katrina Law has had to wield weapons for previous roles. Prior to joining the Training Day cast, Law was best known for her performances as Mira on Starz’ Spartacus and Nyssa al Ghul on The CW’s Arrow. Both roles involved a lot of action, but usually with extensive stunt choreography and old school weapons like a bow and arrow. She could kick ass, take names, and shoot arrows in the middle of battle sequences without skipping a beat; Rebecca’s mastery of a gun was nothing that Law needed for her work as Mira and Nyssa. After all, although Spartacus took its fair share of liberties with history, even the wildest moments didn’t involve the Romans pulling sidearms from shoulder holsters.
