Ong-Bak: Muay Thai Warrior is a 2003 Thai martial arts film directed by Prachya Pinkaew and featured action choreography by Panna Rittikrai. It stars Tony Jaa in the lead role, alongside Petchtai Wongkamlao and Pumwaree Yodkamol.
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 UK) and directed and starred in two prequels of Ong-Bak titled Ong-Bak 2 and Ong-Bak 3.
