This definitely isn't the most sensitive marketing ploy we've ever seen.
A sign featuring Watts dressed as Diana can be seen by the Pont de l'Alma tunnel, just feet away from the gold Flame of Liberty statue which has become known as an unofficial memorial to Prince William and Prince Harry's mother, who died in the underground passageway at age 36.
Diana's untimely death happened in August 1997 while she and her lover Dodi al Fayed were being driven through the Parisian tunnel while being chased by hoards of paparazzi. Their chauffeur crashed in the late hours of the night, killing all three of them.
Rosa Monckton, who was a friend of Diana, told the Daily Mail, "I really don't have any words to describe how I feel about this cynical and shameless attempt to publicize a film that should never have been made. To have made a film so speculative and as this is disgusting enough, but to then advertise it on the spot at which she died is despicable."
"I cannot imagine that any company could stoop so low," Monckton added. "It is a terrible intrusion into her memory, not to mention the lives of her sons, whose feelings are often forgotten in these stories. I would expect them to take it down right away."
Fans visiting the site of Diana's fatal death are known to leave flowers at the Fame of Liberty statue. Graffiti messages remembering the Princess of Wales can also be seen written across the Pont de l'Alma bridge over the tunnel.
