 The ten minutes of sex scenes were considered by Lee to be critical to the story and reportedly took 100 hours to shoot.In a number of countries, notably the People's Republic of China and India, many of the sex scenes had to be cut before the film could be released.In Singapore, while the film's producers initially decided to release a cut version there which was given an NC-16 rating, a public outcry stating that the producers of the film were underestimating censorship standards in the country (the film was released uncut in Hong Kong and Taiwan) prompted them to eventually release the uncut version with the higher R21 rating in Singapore.
