"My guess is that boxing is such a popular subject for filmmakers because people can't imagine what it's like to be a boxer. The blows they take, the training for months on end, actually having the balls to get in the ring. I watched a lot of fights for research, especially some of Tyson's early bouts when his opponents were visibly afraid of him. It must be hard for any fighter who has lost to get up in the morning feeling physically and mentally beaten and then start all over again. Boxing represents sacrifice, and I think that's why audiences find it so captivating." - Joe Sparkes, UK-based animator
