Darren Aronofsky's The Wrestler showcases the sheer physical brutality of wrestling despite the fact that it is staged. In one particularly gruesome scene (one that I wasn't able to find on Youtube sorry), Randy "The Ram" takes turns using a real stapler gun with a fellow wrestler on each other. The dives they take and the chairs and other objects they use to hit each other clearly do very real damage to the amateur wrestlers portrayed in this movie. Mickey Rourke, the actor who plays "The Ram", before filming had very little respect for professional wrestling because of his background as a boxer but quickly after training for the movie he stated that wrestling is just as or maybe even more dangerous than professional boxing. Many of the old retired wrestlers today are banged up physically with many problems and lasting damage from their careers.
The movie also delves deeply into the culture of wrestling. Wrestlers, despite their public animosity towards each other through playing roles like babyface (the good guy) or the heel (the bad guy), have for the most part a great deal of camaraderie with each other and are good friends with each other in private. They plan the bouts together, they commend each other's performances afterwards, and they even share steroids together. Beneath the violence on display in their matches is an obvious respect and caring for each other.
