Actor Jon Bernthal is best known for his roles in The Walking Dead and The Punisher as Frank Castle. In general, it’s fair to say that he often plays a tough guy in these TV shows, especially during The Punisher. One thing to note about The Punisher was the gruelling workout regime that he used to get into shape.
On the show, he often kills bad guys using a variety of martial arts techniques. These include Krav Maga, Judo and BJJ. Whilst this is made for TV and the moves are highly scripted (and to a degree, unrealistic) – it’s possible that Bernthal trained at least some BJJ when preparing for The Punisher role.
However, there is more evidence than that. As seen in the picture of this article, Bernthal is seen wearing a T-shirt that reads Jiu Jitsu. Sadly, there’s been signs of Bernthal training so it can’t be confirmed, but it’s fair to say that he’s at least a fan of the gentle art.
Combining this with his training for The Punisher and some of the fight scenes, you could say that he knows a couple of moves and may have a similar training background as Keanu Reeves. One day we may see Jon Bernthal in a gi…until then who knows?!
