Both movie are using different forms of mixed martial arts. Judo, boksing, wing chun, karate and much more. Both movies are honoring the above arts because both lead actors studied these well and peformed them greatly in the movies.

Both movies are heartbreaking and they are both based on (sadly) true story.. It contains rape, injustice and at the end both movies will leave you crying or speechless, but both movies are worth watching and the actors are amazing, true masterpieces.

They are both great movies and it all revolves around the Gwangju massacre on May 18.
