Though the film has been declared a blockbuster in China, it is also attracting tens of millions of viewers who are downloading pirated versions of the film, containing at least seven minutes of sexual endeavour slashed by China's censors.
Owing to the mass interest, medical officials have taken the responsibility to warn those with access to the uncensored version - 'do not try this at home.'
A reporter for the Information Times surveyed 20 people who had seen the uncensored film, which is set in Shanghai during the Second World War. He also spoke to medical experts about the several minutes of sexual gymnastics, often violent and almost always erotic, that help to describe the attraction between a naive young student and a disloyal and nasty Chinese police chief.
After the survey, the reporter wrote: "Highly difficult sexual positions can cause unnecessary harm to both the male and female body and, hence, people should not be imitating what they see on the big screen."
Yu Zaoze, a gynaecologist with the Guangzhou Modern Hospital told The Information Times: "Most of the sexual manoeuvres in 'Lust, Caution' are abnormal body positions. Only women with comparatively flexible bodies that have gymnastics or yoga experience are able to perform them. For average people to blindly copy them could lead to unnecessary physical harm."
The damage by the film is not only limited to physical harm. A Chinese company focusing on software to combat computer viruses has given warning that pirate downloads of the film could be embedded with viruses and 15 per cent of links were contaminated.
According to local news media, hackers are planting viruses on Websites that provide online video or download services of the film and could infect personal computers if users attempt to download the movie or even click the link.
The film, which is tipped to become the year's biggest box-office success, has been a huge hit in China, reaping 90 million yuan
(6 million pounds) in its first two weeks.
Set in Shanghai during the World War II-era, the film tells the story of a Chinese woman who is recruited to seduce and kill a married enemy collaborator.
