Each Mug Shot is going to have a link to the previous one. So from Mad Max 2 to here. They're sort of trilogies, but sort of not. Three films linked by a central character (referred to on occasion as'The Man with No Name'), but with little to no continuity between them. Max and Blondie/Joe are chancers, alone, lawless but just on the right side of humanity to be heroes. That's to start you off. The next one I probably won't say what the link is.
Anyway. Stuff. I. Drew.
