“Warrior” is the first feature-length film I have seen about “mixed martial arts.” Paddy Conlon (Nick Nolte) has two sons, Brendan (Joel Edgerton), a high school physics teacher, husband and father, and Tommy (Tom Hardy), an ex-Marine. Both sons are estranged from their recovering alcoholic father, a boxing coach -- and there is great enmity between the brothers. Tommy has gone so far as to take his mother’s maiden name, Reardon.
When Tommy shows up at his father’s house to ask him to train so he can fight in a mixed martial arts event, Paddy accepts. He demands discipline and both sons reject all his attempts to make up for his failures when his sons were young.
