Paul Mescal Protects McCartney From Rain During Filming

may well have been taking notes on Friday after joining Sir for a full English at one of London's best known cafes. 

And with principal photography well underway, Mescal, 30, had an opportunity to meet the man in person at Westminster's Regency Cafe, famed for offering the best full English breakfast and a popular filming location courtesy of its art deco interior. 

Dressed in a denim jacket and jeans, the Irish star looked mildly starstruck while exchanging words with the legendary musician on the street after filming scenes - thought to be for an accompanying documentary - inside the Regency. 

McCartney, 83, appeared to be in high spirits while idling alongside Mescal, and little wonder, with the Irish actor on hand to hold an umbrella above his head as it started to rain. 

The actor was last seen playing McCartney on location in Liverpool, with director Sam Mendes and his crew shooting scenes close to the musician's childhood home - now owned by the . 

Mescal was seen enthusiastically riding a vintage bicycle along a leafy suburban street in McCartney's home town after rejoining the crew on location following his appearance at the 79th annual BAFTA Awards.

In a recent interview with Backstage, the actor - whose casting as McCartney has divided fans - shared his admiration for the era-defining musician. 

'I get to play somebody I've always admired,' he said. 'As each day goes by, I just think he's like - you can count on one hand how many people have influenced the world as much as he has.'

Westminster Council told the Daily Mail that they are, in fact, working closely with production teams to facilitate filming, which will involve closing the road.

Starr previously hinted that Saltburn star Keoghan had taken on the role.

He told Entertainment Tonight: 'I believe he’s somewhere taking drum lessons, and I hope not too many.'

Keoghan recently admitted that he wasn't able to because he was overcome with nerves.
