i know this movie..still have it somewhere...sooooooooooooooooooo old..but i don't think there was a thai version
although they did have a lakorn that has similar storyline, i don't know the thai title, but the khmer title is Kchong Sang..and p'ek's name was like..Sang-sao-vachey..something like that, the lakorn where n'ek had 6 older sisters, and they all chose a husband on the same day..in the thai one, p'ek wore a mask that made him look really really dark and an ugly person..but when he takes the mask off, he was nothing but gold..like his attire..i mean..
