A gun is put to a person's head and is threatened.
Boxing matches are shown in the most graphic depiction possible, with lots of blood shown. There is also a shooting and there is blood visible. However there is no gore in this film.
Several intense boxing matches.
During the boxing matches there is often lots of blood on both contestants, especially on their faces. Profuse bleeding is often focused, including bloody teeth and bloody red eyes. Not exactly "gory," but it is fairly bloody.
A fight breaks out between two groups of men.
Someone is shot and the movie focuses on them and their pain. Some blood is visible, but it is not the focus.
Someone dies slowly, and the camera is centered on them. Not very gory.
