Castle in the Air is a 1952 British comedy film directed by Henry Cass and starring David Tomlinson, Helen Cherry and Margaret Rutherford.
The penniless 19th Earl of Locharne, the owner of a run-down Scottish castle which he has made into a mostly empty hotel, has to deal with a myriad of financial troubles, starting with his creditors and the few disgruntled tenants.
Then there is Mr. Phillips, a socialist official from the British National Coal Board, which wants to requisition (not buy) it to convert into a vacation hostel for miners and their families.
Next, a long-time prospective purchaser, wealthy, attractive American divorcee Mrs. Clodfelter Dunne, shows up unannounced to look over the place in person.
When Mrs. Dunne expresses her belief that she is a member of the family, a delighted Miss Nicholson sets out to try to trace her lineage.
