Hoping Hedsor becomes as big as its human co-stars...
Hedsor is still privately owned (for the last four generations, it has belonged to the Shepherd family who now run it as a business).
It has a history going right back to the 12th century - and King George III and Queen Charlotte helped design the present house and chose the location high above the River Thames because of its stunning views. Queen Victoria was a regular visitor from Windsor Castle a century later with historic diary entries of the Royal children playing croquet on Hedsor's lawns.
In the 21st century, like Highclere, it is a favourite wedding venue and location for fashion shoots - but now mega movie exposure may give business a further shot in the arm. And so for the first time over the next few months, Hedsor will be open to the public. Tickets are already selling out.
