After searching online I have managed to locate the Bangkok Girl Documentary by Jordan Clark.
It makes for compelling viewing, and after reading comments online it seems the documentary caused controversy from all sides of the fence. It was produced in 2005 but still feels very relevant, and could easily have been made in the present day. I won’t air my views now, I would rather people had a watch and then perhaps we can exchange some thoughts in the comments section.
Update: You can now read an exclusive interview with the director-producer of Bangkok Girl, Jordan Clark, by navigating to this page.
