with the first pic, he reminds me a lot of that other actor who played rai in kob & brook's movie i think. kob married the rai and died at the end. and another lakorn with mos and aom where he was also rai and got mos sent to prison. i don't know his name.
but yeah, this dude reminds me of that actor when i first saw that pic. as for the other pics, he reminds me of a taller version of oh anuchit.
