The femme fatale Emmanuelle Poirot is not only a tribute to Agatha Christie's famous detective Hercule Poirot (who is her grandfather) but also to the Emmanuelle erotic films, particularly Emmanuelle (1974) which was also set in Bangkok.
Emmanuelle's costume during the disco sequence is Charlotte Rampling's infamous costume from The Night Porter (1974).
In the disco sequence, you can see C-3PO from Star Wars: Episode IV - A New Hope (1977) and Bugs Bunny.
Also known as "Emmanuelle in Bangkok."
