The Curzon Mayfair cinema has been saved after developers threatening to sink the historic London venue backed off.
Developers 38 Curzon Ltd are converting office space about the venue into luxury flats and complained about noise from the cinema. Their complaints were backed by Vevil International, the building's owner.
The developers claimed the noise levels were a breach of the cinema's lease and that it must pay for soundproofing, which would cost the Curzon £500,000, a bill the cinema could not afford.
The argument led to legal action, and the Curzon faced having to give up its lease.
But, after outcry in the local community and beyond, the cinema must no longer defend itself against a lawsuit.
The news comes after London mayor Sadiq Khan stepped in, vowing to make changes to the London Plan protecting venues like the Curzon Mayfair.
He said that, in future, developers would have to pay for soundproofing if they were worried about noise coming from London venues.
In a joint statement, the developers and cinema staff said: "Over the past few months Curzon Cinemas and Vevil International have been working together to ensure the continued success of the Curzon Mayfair and peaceful coexistence with local residents.
"Both are delighted to have resolved the issues and look forward to a fruitful working relationship. They would like to thank all those who took an active interest."
