Prequels
After Ong-Bak became a huge worldwide hit, Jaa's name was attached to many projects. He went on to act in a small role in the Petchtai Wongkamlao vehicle, The Bodyguard (co-directed by Panna Rittikrai), and then starred in the much-anticipated Tom-Yum-Goong in 2005. In March 2006, it was announced that filming for Ong Bak 2 would start that fall and the film would be a prequel to the original. The film was eventually released in December 2008, with Jaa debuting as director.
A second prequel, Ong Bak 3, followed where the second film left off. This means that Ong Bak takes place chronologically after Ong Bak 2 and Ong Bak 3.
