I don't know Tony, neither have I seen Tom Yum Gung, but with your description of Tom Yum Gun as one of the Thailand food which taste sour and spicy, then the title must be a parable with a mixed feelings... Just my idea.
Tony is actually so rough in filming that many international stunt doubles quit or got injured during filming.
This is so funny, I think Tom love it real, if you are not ready to make it real or at least look real, don't come near him... Ahahhahaha.
