Oscar-winning actor Colin Firth has completed six weeks of filming in Cumbria.

Firth, 59, was making a film called Supernova, co-starring American actor Stanley Tucci. It was filmed mainly in the Lake District.

Last Saturday night Firth visited the Keswick Alhambra cinema to watch Judy, a drama about Judy Garland. It stars his Bridget Jones’s Diary co-star Renée Zellweger.

Co-owner Carol Rennie said: “Colin came to the Alhambra with nine others involved in the film he’s shooting. I’d taken a call asking to reserve 10 balcony seats which would be paid for when they came.

“Usually we take full payment in order to reserve seats, but for some reason the lovely girl who made the call managed to reassure me that they would most definitely be coming, so I took the booking.”

Assistant manager Helen Smith was on duty that night. She spoke to Firth after the film and gave him a tour of the recently refurbished cinema.

She said: “I told him we used to have a Colin Firth picture up in the gents loo a few years back and he thought that was hilarious.

“When I asked if I could get a picture he said ‘Where do you want me?’

“He was really nice, and had a laugh and a joke when I said I was embarrassed about asking him to pose next to a radiator! He said that he and his friends were all very impressed with the Alhambra. It was a real pleasure meeting him in our lovely little cinema.”

In Supernova, Firth and Tucci play Sam and Tusker, who have been partners for 20 years.

Since Tusker - played by Tucci - was diagnosed with early-onset dementia, they have given up their jobs and put their plans on hold.

They are travelling across England in their old campervan visiting friends, family, and places from their past.

As the trip progresses, secrets are uncovered, plans unravel, and their love for each other is tested like never before.

The film was written and directed by Harry Macqueen.

He said: “Supernova is a deeply romantic, modern love story. It follows two people who are bound together by their love for each other, but being pushed apart by the situation they find themselves in.

“It is an intimate, naked portrayal of a relationship facing a fissure that threatens to cut it to its very core.

“Supernova is an empowering, powerful and challenging film about what we are willing to do for the people that we love.”

Filming began in September at locations including Crummock Water, Keswick, and Café 66, on the A66 near Appleby.

Firth and Tucci are friends, having worked together on the 2001 film Conspiracy and 2012’s Gambit.

Early in their stay in Cumbria they called at The Sun Inn, Bassenthwaite, for Sunday lunch. The pub’s Facebook account published a photograph of a staff member with the actors.

Firth is among the most critically acclaimed and commercially successful actors in the world. He came to prominence in 1995 when starring as Mr Darcy in the BBC’s production of Pride and Prejudice.

He has had notable roles in films including Love Actually, Mamma Mia! and A Single Man.

In 2011 he won the Best Actor Oscar, a Golden Globe and a Bafta for his portrayal of the future King George VI in The King’s Speech.

Tucci, 58, was nominated as Best Supporting Actor at the 2009 Academy Awards for his role in The Lovely Bones.

His other film credits include The Devil Wears Prada and The Hunger Games.

Supernova is produced by Quiddity Films and The Bureau. Its financiers are BBC Films and the BFI. Distribution deals have already been struck for countries including Germany, Japan and Taiwan.
