Best mma movie of all time

I know there's other mma movies out there, but i think this movie beats them all. Its about two guys that are having troubles in their life One guy is a teacher and the other is a lost marine. The teacher is needing money to save his house and the marine is looking for a way out. through out the movie u watch what troubles they have. In the middle of it all they find out that there is a BIG fight,  Any body that's anybody can fight only sixteen. fighters and they can range from a Joe smo  to a ufc fighters and they have to fight the champion of the UFC. and the winner get 5 miilion dollars. And the two guys are related you didn't see that coming did you. Again im leaving you wondering  you need to see this movie let me know what you think even if you've already saw it. Heres a trailer.
