Chat Achanai (lost Thai action film)

Chat Achanai (ชาติอาชาไนย) was an action film that has been lost ever since it's original screening in 1975. Despite the fact that it was a hit back in the 70's, the only thing left of this film are the countless promotional material along with one two-minute long teaser. This teaser is believed to be the last remaining footage of the film, but there is a chance that the original negatives are somewhere. The film was locally made in the province of Roi Et.
