With Ong Bak 2 (2008)'s very troubled production (running over budget, over schedule, looking to have a running time of over four hours,...), it was decided to split it into two films, with this resulting third part thus consisting of unused material shot for the second film by Tony Jaa and new footage by director Panna Rittikrai who was brought on board to save the two films and came up with Dan Chupong's character Bhuti Sangkha, introducing him in the second film to set him up as the main villain of this film. As a result of the pressures of making the films and conflicts with the production company, Jaa retired to a Buddhist monastery for about a year once the film was released.
In late 2012, a video game based on the Ong Bak films was revealed to be in production. Taking place in ancient times like the second and third films, the developers revealed in an early 2013 interview that the game was a prequel to a new film in the series that would soon be announced. Said film announcement never occurred however and the game was never released.
