Thank you. My wife lived in Austria. I will ask her if she has been there.
shareThe castle and train station location is Werfen in Austria near Salzburg, as it states in the film. most of the village shots are in Lofer near Salzburg, and the cable car, and river is shot in Ebensee, south east of Salzburg, all well worth a visit
All the interior scenes and top cable car station are all shot at the late Bornhamwood studios in England.
The castle is open to the public and has the film showing on a small screen in a room.
See for yourself. Use the wonderous power of Google Earth.
