Starring Joel Edgerton as the man fighting to keep his family's roof over their heads and Tom Hardy as an absolute animal (pre-Bane) who is fighting to support his departed military comrade's family, whilst rivalling his brother over dark family history, this film is inspirational to those who train for any contact sports from the training through to the fights themselves.
The black and white theme is very strong and gives you a sense of the drama involved with the storyline. Somehow there is mild warmth provided with the orange/ gold "FIGHT FOR FAMILY" line, which is appropriately placed in relation to the character. Perhaps an effect that colour has on our beings at a subconscious level.
As a comparison, here's the Tyson vs Holyfield fight poster, which is a similar fight promotion poster that the Warrior's film poster is based on.
