It makes too much sense to cast Ciryl Gane in an action movie. On one hand, he’s a professional MMA fighter, a heavyweight no less. At six-foot-five, he’s a 250 pound wall of muscly giant, with a unique blend of physicality and martial arts acumen to more than sell an on-screen fight. On the other hand, however, he also has an adorable baby face, complete with a goofy smile that often makes it difficult to take him seriously as a badass. It's hard to say this massive, scary dude is cute, but…he kind of is. Fortunately French director Antoine Blossier knows how to make good use of both of these facets in his new movie, K.O.
