Yuthlert often makes in jokes and references to his own films. In "Sai Lor Fah", a character is encouraged to be just like "Kit Silencer", the lead character from "Killer Tattoo". Also, a character in "Sai Lor Fah" was trying to buy an unlicensed DVD of "Buppah Rahtree 3", a sequel that hasn't been made. In "Ghost Variety", a film directed by Adirek Wattaleela (a producing partner and character actor in Yuthlert's films), Yuthlert had a cameo (as did dozens of other Thai filmmakers). The characters in "Ghost Variety" burst into what they thought was a haunted house, but turned out to be a movie set of "Buppah Rahtree 3".
