Ong-Bak: Muay Thai Warrior, also known in the United States as Ong-Bak: The Thai Warrior is a 2003 Thai martial arts action film. It was directed by Prachya Pinkaew, featured stunt choreography by Panna Rittikrai and starred Tony Jaa. Ong-Bak proved to be Jaa's breakout film, with the actor hailed internationally as the next major martial arts star. Jaa went on to star in Tom-Yum-Goong (called The Protector in the US and Warrior King in the UK) and directed and starred in two prequels to Ong-Bak: Ong-Bak 2 and Ong-Bak 3.
