In the world of action cinema, and especially in the niche martial arts movie subgenre, fans will quickly identify their favorite on-screen talents. The A-listers stand tall in the minds of most fans. Maybe Donnie Yen's decades in the field won them over. Perhaps Iko Uwais' raw talent and screen presence speak to something fundamental in the art form. Maybe Jackie Chan's incredible stunts and sense of humor still land perfectly. There's often not enough love for B-list martial arts icons like Scott Adkins. His Ninja films are a love letter to the fun and charm of classic video store martial arts material.
