introduced international audiences to a traditional form of muay Thai (or Muay Boran, an ancient muay Thai style), a kickboxing style that is known for violent strikes with fists, feet, shins, elbows, and knees. The fights were choreographed by Panna Rittikrai, who was also Tony Jaa's mentor and a veteran director of B-movie action films. Jaa, who was trained in Muay Thai since childhood, wanted to make the film in order to bring Muay Thai to the mainstream. He and Panna struggled to raise money to produce a demo reel to drum up interest for the making of the film. Their first reel was made on expired film stock, so they had to raise more money and start over. During the foot chase through the alleys, there is writing on a shop house door that reads "Hi Speilberg, let do it together" [sic]. This refers to the director's desire to someday work with Steven Spielberg. During the tuk-tuk chase, a pillar on the left side of the screen reads: "Hi, Luc Besson, we are waiting for you." The French producer-director's company, EuropaCorp, would go on to purchase the international distribution rights to the film.

EuropaCorp also re-scored the soundtrack with some hip-hop sounds, replacing the Thai rock score; this is this version that has been made available in the United States and most of the Western world. For the United Kingdom release, the soundtrack was scored yet again; this time with an orchestral score, but the film was left uncut with the subplot of Ngek. The Hong Kong cut of the film's theatrical release omits a "bone breaking" sequence toward the end, where George's arm is snapped and Ting in turn snaps the leg of a bad guy. DVD releases in Hong Kong have the scene restored. An alternative ending offered on the Thai, U.S., Australian, and UK DVD releases has Humlae surviving. He is seen at the end bandaged up, limping, with his arm broken, supported by his parents. Prachya Pinkaew stated in an interview that although there was debate, they ultimately decided it would be appropriate for him to make a
