The Thai movie The legend of King Naresuan is scheduled to be released in December. For an interview with the director see this English reading lesson for last week's Bangkok Post.
The film is sort of a sequel to the film Suriyothai which was more about court intrigue than this film which will be more about warfare. The director talks about how he has tried to avoid Thai nationalism in making the film, but how certain parts of the film like how Naresuan recruits the Mons to be on his side may be controversial to the Burmese government.
