Mundane History

Mundane History is a 2009 film by the Thai film-maker Anocha Suwichakornpong. She wrote, co-produced and directed the film. It is described as “one of the most startling and original feature debuts of recent years", and received its world premiere on 10 October 2009 at the 14th Busan International Film Festival in South Korea. It was the first Thai film to receive the country's most restrictive viewing rating, due to a scene of full-frontal male nudity and masturbation.
