10 Best Wrestling Documentaries Ever

CM Punk's acrimonious split with WWE three years ago makes this documentary - produced in 2012, back when things were (sort of) rosey - even more significant, given that is looking, increasingly, like there will be little else to add to the wrestling career of one of the biggest stars of the modern era.

Though it is, inevitably, a little WWE-heavy, Best in the World makes little effort to whitewash the early days of Punk's career, featuring grainy footage of the Straight Edge Superstar's formative years, working his way up the independent scene ladder and, all the while, developing his now iconic in-ring persona.

And given that Phil Brooks, at the time, was playing an anti-establishment anti-hero with an enormous Triple H-sized chip on his shoulder, there doesn't seem to be too much in the way of censorship either. Punk, along with advocate Paul Heyman, talks candidly about the struggles and concerns he had after getting to the big time.

It's honest, compelling, and - this bears repeating - with Punk now determined that he won't get back in the ring, it's probably also the Definitive CM Punk Collection (whether you like it or not).
