EAGLE-eyed movie fans could spot parts of Hemel Hempstead in the new film based on Princess Diana.
Film crews descended on the town on Sunday and are expected to depart tonight.
Production trailers have been sited in the former ‘park and ride’ area of Gadebridge Park, while filming takes place within the park and at other locations around the town.
The crew is working on the film Diana, which has previously been referred to by its working title Caught n Flight in national press reports.
It tells the story of Diana’s relationship with heart surgeon Dr Hasnat Khan and will include the infamous crash that claimed the life of the much-loved royal in 1997.
The makers have permission from Dacorum Borough Council to set up base in the town, but there’s no charge for the privilege.
Council spokesman Katie Warner said: “It is the local community that really benefits from filming coming in. It benefits the local economy.”
Charges only apply if a production company wants to hire council-owned property.
Diana, due to be released in 2013, stars actress Naomi Watts as the Princess of Wales and is directed by Oliver Hirschbiegel, who is famous for his portrayal of the last days of Hitler in Downfall.
Dacorum is a favourite with film makers because it’s close to London but offers picturesque locations like the Ashridge Estate where scenes for Harry Potter, Robin Hood, Son of Rambow and many more were shot. Historic Gaddesden Place is regularly used as a backdrop for film, TV and photography work.
