Poster for Diana film appears outside Parisian tunnel where the Princess died A poster advertising the new film Diana has been installed next to the road tunnel where the Princess of Wales died. The film poster, which shows actress Naomi Watts as Diana, has appeared on a billboard advertising sign next to the Pont de l'Alma in Paris. The move comes as the new film, which has been slammed by critics in Britain, opens in France this week. The Independent's Anthony Quinn gave the film one star, saying: "Diana opts for Mills and Boon, a would-be tragic romance that spares us nothing in soppiness or banality." The film chronicles Diana's romance with Dr Hasnat Khan which ended in 1997, just a few weeks before her death. Diana was with then-boyfriend Dodi al Fayed when they died in a car crash in the Pont de l'Alma tunnel on 31 August 1997. An inquest in 2008 found they had been unlawfully killed, partly due to the "gross negligence" of their driver Henri Paul, who was found to be drink driving.
