Saw this yesterday and it was fantastic, beautifully shot and filmed and has a proper plot and storyline that develops throughout. I heartily advise anyone who likes martial arts films to watch it.
Its set in the past during some sort of thai dynasty period of war.
Is is the Ong Bak 2 that was released here a couple of years ago, original title being Tom Yun Goong (the one about the baby elephant, set partly in Australia), or the recent 'official' sequel from last year?
