Improvements worth £100,000 were made to a stately home in Nottingham for the filming of the new Batman movie.
Scenes from The Dark Knight Rises were shot at Wollaton Hall in June and July last year.
Warner Brothers paid for redecorations to The Great Hall and entrance hall and re-gilded some windows at the back of the property.
The studios also paid a fee to use the Elizabethan house as Wayne Manor - Batman's home - in the movie.
Ron Inglis, from Nottingham City Council, could not disclose the hire fee but admitted the "sum was appropriate to the amount of disruption".
Wollaton Hall and Park was closed while filming took place during June and July, in 2011.
Mr Inglis, the council's service manager for museums and galleries, said: "They wanted quite significant changes.
"Everything was done to an appropriate conservation standard. Nothing was done that was out of keeping with the hall."
David Trimble, council cabinet member for culture, said it was an "incredible opportunity" when Warner Brothers approached the authority.
He said the film, which comes out in the summer, would increase visitors and bring benefits to the local economy.
The Dark Knight Rises, which stars Christian Bale, Gary Oldman and Anne Hathaway, will be in cinemas this summer.
