John Wick: 2011
Chapter 2: 2017
Parabellum: 2019
Keanu Reeves trained seriously hard for the John Wick role. I've added an extra link at the bottom of this page of him in training on the shooting range... He became quite the tactical operator. His Martial Arts training was just as rigorous. In Parabellum he clearly trained more in Brazilian Jui-Jitsu than in the previous movies, but Krav Maga is still used in the bulk of his combat scenes.
