Boyka! Boka! Boyka! The English (not Russian actually) actor/martial artist behind the fictional character Yuri Boyka, he has trained in Gymnastics, Judo, Jujutsu, Taekwondo, Karate, Kickboxing, Wushu, Capoeira, Krav Maga, Jeet Kune Do, and even Ninjutsu. Having as varied of a martial arts background as other stars like Donnie Yen and Michael Jai White, he is one of the most underrated cinematic martial artists of this generation. Here's a compilation of my favorite Scott Adkins fight scenes.
