Probably one of the last fighters I'd think that would make a good movie star. It'll definitely be interesting to see.
I don't want to be mean but I don't think Nick Diaz and his brother can remember long lines on text to be good actors but you never know 
Some people surprised me and they turned good actors with lot of hard work like Dave Bautista for example.
Someone can correct me if I am wrong but Randy Couture, Georges St-Pierre, Quinton 'Rampage' Jackson and Ronda Rousey all had some acting roles.
I wonder if Nick Diaz will also receive this famous kick
Or maybe Nick Diaz will be villain trying to kill Van Damme like this in Universal Soldier
