Region 1 DVD and Blu-ray.
Peter Nellhaus has a review at Coffee Coffee and More Coffee.
Headlined by a cast that includes Ananda Everingham as the warlord, Cherman Boonyasak as his wife and Mario Maurer as the monk, the film was released in 2011 as U Mong Pa Mueang (อุโมงค์ผาเมือง) with the provisional international English title of The Outrage, which was the same as the 1960s Hollywood western Rashomon remake that starred Paul Newman and was directed by Martin Ritt (check out Hombre instead).
The release of U Mong Pa Mueang in Thailand was heavily promoted, thanks to the star power of Ananda and Ploy Chermarn, who had previously starred in "Mom Noi" Bhandevanov's hit erotic drama Chua Fah Din Salai (Eternity). It was also a tie-in with the centennial birth anniversary of Thai statesman, author and artist MR Kukrit Pramoj, who had translated a stage version of Rashomon, which Mom Noi had a one time directed. He then used the stage version as the basis for his film adaptation.
The DVD package, featuring Ananda and the bandit (Dom Hetrakul) swordfighting against a backdrop of a Thai-style structure, touts the awards and nominations of U Mong Pa Mueang – Asian Film Awards noms for Mario and costumes, Bangkok Critics Assembly Awards for art director and supporting actress for Radklao Amaradit as the medium, and Subhanahongsa Awards for costumes and visual effects.
