Campaigners battling to save the historic Kensington Odeon took their fight to Whitehall on Thursday (August 27) afternoon.
Armed with placards they gathered outside the Department for Culture, Media and Sport after delivering a petition signed by more than 25,000 people.
The cinema is due to close for good on Bank Holiday Monday (August 31) with real estate investment and advisory company Delancey planning to replace it with flats and a new picturehouse.
But the iconic building - which includes an Art Deco exterior, marble staircase and a mosaic floor in the foyer, is much-loved in the community.
Campaigner Paul Wiffen said: “The Odeon has moved forward their closing date to this coming Monday so we are very worried the bulldozers may roll in.
“I’m going to be standing in front of the cinema on September 1 to make sure they aren’t going to knock it down.”
Diana would reportedly often take Princes William and Harry there, while it is also popular with Kensington-born Sherlock Holmes star Benedict Cumberbatch, who would regularly visit the cinema in his youth.
The petition was started by Don Walker, who collected 20,000 physical signatures.
Then an online petition was also set up which read: “We risk losing a magnificent iconic community venue. Kensington does not need any more empty luxury flats being bought up by foreign investors.”
Actors Benedict Cumberbatch , Kristin Scott-Thomas and Sir Ian McKellen, director and writer Richard Curtis, and legendary guitarists Brian May from Queen and Led Zeppelin’s Jimmy Page have all signed up to fight plans to replace the historic cinema.
One resident Jeremy Conrad at the protest on Thursday said: "I've lived in Kensington a long time and my earliest cinema memories are at Kensington Odeon.
"I saw the jungle book there when I was three. My daughters have been there too.
"It is really sad they're going to replace it with a generic cinema and flats."
Mr Wiffen said: “Benedict Cumberbatches’ parents would bring him to this cinema every Saturday most of his childhood, you could say it’s where he learned to act. This is his childhood cinema.
“So it’s particularly sad that Benedict’s production of Hamlet which is being simi-cast in Odeons around the country has had to be cancelled it probably won’t be there.”
“But we are not giving up. The bulldozers may move in but we will continue to stand out on Tuesday (Sept 1) and continue to get the petition signed.”
A spokesperson Delancey, the project's development managers said: "“Following the council’s decision to approve our planning application, we are progressing with our plans to upgrade the cinema facilities by delivering a new Picturehouse Cinema with 7 state-of-the-art screens, restoring the building’s historic façade and providing a vibrant café, bar and restaurant.
“The scheme will retain the two London plane trees in front of the cinema and deliver 20 affordable homes for the over 55s.”
