Some close friends and fans of the late princess have criticized the move as exploitative and insensitive.
"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," People.com quoted Diana's friend Rosa Monckton as saying. "To have made a film so speculative as this is disgusting enough, but to then advertise it on the spot at which she died is despicable. ... 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 now."
