This site is so much fun as you can find out where many well loved movies were filmed.
One of my all time favorite movies, Jane Eyre in it's many incarnations was filmed at Haddon Hall (for the Thornfield Hall scenes) in Derbyshire, and Chatsworth House also in Derbyshire has been used for Pride and Prejudice. Hardwick Hall was used for some scenes in Harry Potter, and Highclere Castle is Downton Abbey. You can check out my pages to the left to see pictures of my own visits to these places, and go to the site below to find out information on the locations of your own favorite movies.
