Film crews are believed to be preparing an airplane crash scene at West Wycombe Hill, fuelling speculation that Hollywood star Brad Pitt could be visiting the town to film a scene for his new World War Two movie.

Eagle-eyed residents have this week spotted film crews setting up at West Wycombe Hill, near the Mausoleum, and a walker at the National Trust site also claims to have been told that the film company on site is preparing an air crash scene, which is expected to be laid out by Tuesday.

WWII romantic thriller, Five Seconds of Silence, starring Brad Pitt, Lizzy Caplan and Marion Cotillard, is due to start filming at West Wycombe Hill in spring this year, according to the national trust site’s Wikipedia page.

Set in 1942, Paramount’s Five Seconds of Silence follows a spy who falls in love and marries a French agent during a dangerous North African mission and is due for release in the USA in November.

Brad Pitt has already been spotted filming in London this week and the star is believed to be living in the UK for around six months with his family.

The National Trust has not yet commented.
