Quotes from Brin-Jonathan Butler

We're a long way away from someone like Willie Pep winning a round without throwing a punch.

In the documentary 'Facing Ali,' nearly half the fighters involved required subtitles despite speaking English, their speech slurred by the physical toll of their ring lives. This was their reward for testing their furthermost physical and mental boundaries.

My mother left Hungary as a refugee, and she is not nostalgic for the life that she had back in Hungary, and yet Cubans certainly want the economic opportunity in the United States, but they're desperately homesick for the culture that they left behind.

I'd never seen Rigondeaux's face without it being obscured by headgear or a photograph of Fidel he was holding up after winning a tournament. Finally I saw him, only to recognize the saddest face I'd ever seen in Cuba.

Exploring Castro's pawns in Cuba and exposing anything negative also makes you a pawn to all his enemies 90 miles away. Both sides don't have much of a track record for nuance of opinion.

Cuban athletes represent the most expensive human cargo on earth. They are sitting on over a billion dollars of human capital if these boxers and baseball players would come over to any other field or ring in the world and begin to ply their trade.

Galileo wasn't put in prison because he was wrong about anything he discovered looking through his telescope; rather, he was incarcerated simply because he saw what others didn't wish to see.

In film or on stage, in reflecting life through art, an actor has a second take or another day with his or her performance if something goes wrong. Bullfighters are spies crossing into enemy lines. Any mistake, no matter how minor or trivial, is potentially fatal.

Castro branded Rigondeaux a 'traitor' and 'Judas' to the Cuban people.

Rigondeaux was Cuba's answer to Bobby Fischer who transformed into a kind of Lee Harvey Oswald traitorous creature in that society. He escaped on a smuggler's boat and toppled one of the best fighters in the world in 2013 with his obliteration of Nonito Donaire at Radio City Music Hall. He made it look so easy, his career has never recovered.

'What comes next?' is the constant question I'm asked by outsiders eager to travel to the island. During the eleven years I traveled to Havana, very few Cubans I met on the island ever bothered to verbalize this question.

I traveled to Cuba with the intention of speaking with boxers who had turned down enormous offers to leave. When explaining my project to people, again and again I was met with amusement and skepticism.

A profoundly disturbing thing you discover very quickly traveling in Cuba is that the most dangerous person for Cubans isn't the police or even the secret police; it's their neighbor. Anyone can report you for anything 'outside' the revolution - even if you haven't done it yet.

As far as cities go, Havana is a festering treasure chest, a primary color.

Trusting the world is a risk, while not trusting it is a guarantee you'll be left with nothing.

Castro was always using his athletes as a way of symbolically defeating the United States in the ring, and after these Cubans defeated Americans in the ring, they were turning down exorbitant sums to leave the island.

When Mike Tyson was only 18, his managers used to market him on posters, reminding you that if your grandfather had missed Joe Louis, or your father Muhammad Ali, don't you miss Tyson.

On June 27, 1988, a 21-year-old Mike Tyson made in excess of 21 million dollars for 91 seconds of work. It took him just over 14 seconds to pull in more money than Michael Jordan, in his prime, made for an entire season of work that year.

Mike Tyson notoriously looked for a way out against Evander Holyfield when it was clear Holyfield had his number. Suddenly, Tyson's cowardice in gnawing off Holyfield's ear overshadowed nearly everything he had accomplished as a fighter.

My documentary 'Split Decision' examines Cuban-American relations, and the economic and cultural paradoxes that have shaped them since Castro's revolution, through the lens of elite Cuban boxers forced to choose between remaining in Cuba or defecting to America.

Hundreds of years ago, the most beautiful women of Havana were only glimpsed stepping in or out of carriages on this street. The first foreign writers who arrived and saw this could never get past just how incredibly beautiful their feet were.

With all of the people in Cuba who I met - many of them hugely heroic figures - I found learning about their complexity and richness and contradictions just really fascinating, and it was fulfilling to be able to offer a different side to them, to be able to have some kind of unique takeaway from the official narrative.

When I first asked my boxing coach, two-time Olympic champion Hector Vinent, what made the Cuban style of fighting distinct from the rest of the world, he smiled and told me to sit on a bench in Prado and watch the Cuban women walk.
