Mixed martial arts is a sport that has, over the course of the past three decades, undergone one of the most remarkable transformations in sporting history.
What began as a largely underground activity, viewed with suspicion and hostility by sporting authorities and the public alike, has become one of the most watched combat sports on the planet.
Documentaries have played no small part in that transformation, helping to humanise the fighters and explain to a wider audience what drives people to compete in such a physically demanding and dangerous discipline.
Picking the best ones is an excellent way to be introduced to the sport.
The Smashing Machine: The Life and Times of Extreme Fighter Mark Kerr
If you are looking for a documentary that will challenge any preconceptions you might have about mixed martial arts and the people who compete in it, The Smashing Machine: The Life and Times of Extreme Fighter Mark Kerr is an excellent place to start.
Directed by John Hyams and originally produced for HBO, the film follows Mark Kerr, a two-time UFC heavyweight tournament champion who was considered to be one of the most fearsome fighters in the world at the height of his powers. What makes it such a compelling watch, however, is the way in which it refuses to look away from the difficulties he faced outside the cage.

From his struggles with addiction to the toll that years of competing at the highest level had taken on him both physically and mentally, this is a documentary that is willing to look at its focus warts and all. It is a film that treats its subject with genuine compassion and curiosity, whilst Kerr’s willingness to allow the cameras such intimate access to his life gives it a raw honesty that is extraordinary to see.
Widely regarded as one of the finest MMA documentaries ever made, it remains essential viewing more than two decades after its release. It was also made into a fictional version starring The Rock in the role of Kerr.
Choke
Long before the UFC had become the global entity it is today, the Gracie family of Brazil were the most famous name in combat sports and Choke offers a fascinating window into that world. The film follows Rickson Gracie, widely regarded as one of the greatest Brazilian jiu-jitsu practitioners of all time, as he prepares for the 1995 Vale Tudo Japan tournament in Tokyo.
At the time of filming, Rickson Gracie was undefeated in competition and what the documentary captures so effectively is the extraordinary discipline and focus that went into maintaining that record, following him into what was thought of as the World Cup finals of the sport.
Alongside the tournament preparation, viewers are given a glimpse into his daily life, including his approach to meditation, breathing techniques and his relationship with his family, all of which combine to paint a portrait of a man whose entire existence was organised around the pursuit of physical and mental excellence.
For anyone interested in the roots of modern mixed martial arts and the philosophy that underpins it, Choke is a genuinely enlightening watch, culminating in seeing Gracie looking to fight three times in one night in order to defend his title. It is a brutal and honest portrayal of a no-holds-barred sport.
Fightville
Not every documentary about mixed martial arts concerns itself with world champions and global superstars. Fightville is all the more interesting for steering away from the mainstream aspects of the sport. Instead, directors Petra Epperlein and Michael Tucker allow the film to take a close look at the world of regional MMA in Louisiana, following a group of fighters as they attempt to work their way up through the lower levels of the sport in the hope of eventually making it to the big time.
Among those featured is a young Dustin Poirier, who would go on to become one of the most celebrated fighters in UFC history in the years following the film’s release.
At the time of filming, though, Poirier was just another promising prospect trying to catch a break. The documentary is also notable for the attention it pays to Gil Guillory, the owner of a small local promotion who funds his shows largely out of his own pocket. His struggles to keep his organisation afloat give the film a moving quality, exploring why it is that someone would put so much of their own finances and time into something that they get little from in return.
The documentary is a portrait of a sport from the bottom up, rewarding viewers for deciding to look away from the mainstream into a more interesting part of events.
Conor McGregor: Notorious
Whatever your opinion of Conor McGregor the person, and it is fair to say that there are many that do not think he’s a particularly nice guy, it is very difficult to argue that his rise from the working-class suburbs of Dublin to the pinnacle of the UFC is anything other than an extraordinary story.
In Notorious, McGregor’s story is told with considerable energy and flair that the man himself would be proud of. The documentary, which was made with McGregor’s full cooperation, follows his journey from his early days as a plumber’s apprentice supplementing his income with welfare payments, through to him becoming one of the most successful fighters in UFC history.

He was the first person to hold titles in two weight classes simultaneously, which was a remarkable achievement. Along the way, the documentary captures some of his most iconic fights and press conferences, as well as offering a more personal look at his relationship with his family and his long-term partner Dee Devlin.
There are those who feel that films made with such close access to their subject inevitably sacrifice a degree of objectivity and that is perhaps a fair criticism here and punches are definitely pulled. As a document of one of the most compelling careers the sport has produced, however, it is a gripping watch.
The Hurt Business
For those who are interested not just in the individual fighters but in the sport of mixed martial arts as a broader cultural and commercial phenomenon, The Hurt Business offers a thoughtful and wide-ranging examination of how MMA grew from a niche activity into a mainstream global enterprise.
Stylised as THE HURT BUSINE$$ and directed by Vlad Yudin, the film is narrated by Kevin Costner. The documentary begins by looking at the history of the sport from its controversial early days, when it faced bans in numerous American states and was denounced by politicians and commentators as human cockfighting.
From there, the documentary moves to look at MMA’s eventual establishment as one of the most watched combat sports in the world. Along the way, it speaks to a number of prominent fighters about their experiences both inside and outside the octagon, exploring the physical toll the sport takes on those who compete in it and the financial realities that many fighters face lower down the pyramid, in spite of the UFC’s considerable commercial success.
Unlike Notorious, it is not a film that pulls its punches. Instead, it looks at the nooks and crannies of a world that perhaps only the most dedicated fans will really enjoy.
Anderson Silva: Like Water
Anderson Silva is widely regarded as one of the greatest mixed martial artists of all time, holding the record for the longest title reign in the history of the sport. In Anderson Silva: Like Water, we are offered a rare and intimate look at what life was like for the man at the very peak of his powers.
The documentary follows Silva as he prepares for his 2010 middleweight title defence against Chael Sonnen, a fight that would go on to become one of the most talked-about bouts in UFC history. For obvious reasons, the film cannot entirely anticipate quite how remarkable the fight between the pair would turn out to be.
What it does capture, however, is the manner in which Silva prepares to take on Sonnen, blending the physical demands of training with a deeply spiritual philosophy that draws on his Brazilian roots and his background in capoeira and Muay Thai. There is a stillness and a quietness to the film that sets it apart from many MMA documentaries, which tend to emphasise aggression and intensity above all else.
For those who want to understand what separates a truly great fighter from a merely very good one, Like Water provides some genuinely illuminating answers. It is also more than happy to explain precisely why many disliked Silva’s approach to fighting that ‘embarrassed’ Dana White.
