They play lovers in their upcoming romantic fantasy film All of Us Strangers.
And Paul Mescal and Andrew Scott proved they’d become the best of friends as they larked around at a screening for the movie on Monday.
The actors seemed in high spirits as they posed for pictures and shared a giggle while promoting their work in Los Angeles.
Paul, 27, put his muscular physique on display as he layered a tight fitting black T-shirt over a white top, pairing the look with wide legged grey trousers.
Andrew, 47, also looked stylish as he teamed a mint green striped cardigan with fitted black trousers with loafers.

The actors star in All of Us Strangers as neighbours, living in contemporary London, who become lovers after a chance encounter, but find themselves haunted by memories of the past.
It begins as writer Adam (Andrew) returns home one night and catches a glimpse of Harry (Paul) from the street below their high rise apartment block.
Harry then pays Adam a visit admitting that he saw him ‘starring’ from the street and had assumed he was single as he ‘never sees him with anyone.’
But as romance blossoms between the pair Adam becomes increasingly preoccupied by memories of his past.
Adam returns to his childhood home where he discovers that his dead parents (Claire Foy and Jamie Bell) appear to be alive but have not aged a day in 30 years.
After welcoming their son back home, the family sit down for dinner together at the table.
The film is an adaptation of Taichi Yamada’s 1987 Japanese psychological novel Strangers.
Director Andrew Haigh has said that Paul and Andrew were ‘fearless’ when filming their sex scenes in the new movie.

The filmmaker praised the work the two Irish actors did on the flick which is based on the 1987 novel Strangers by Taichi Yamada.
Speaking to Vanity Fair, he said: ‘There was chemistry between the two of them literally the second I saw them together.
‘Both of them were pretty fearless. There was no sense of them being afraid of approaching those scenes. They knew how important they were.’

Haigh is known for directing and writing the screenplays for the films Weekend and 45 Years and he also directed HBO’s gay drama series Looking.
The director added that he was determined to cast a gay actor in the role of Adam, which went to Andrew.
He also said he doesn’t believe that only gay actors should play gay characters.
He said: ‘I’m not one of those people who thinks you have to cast a queer actor in a queer role.
‘But for this role, I did want to because I was trying to unpick some nuances of a certain generation of gay people.’
Golden Globe nominee Andrew previously discussed his sexuality in a 2013 interview with The Independent, saying he didn’t want to ‘trade on it’.
He said: ‘Mercifully, these days people don’t see being gay as a character flaw.
‘But nor is it a virtue, like kindness. Or a talent, like playing the banjo. It’s just a fact.
‘Of course, it’s part of my make-up, but I don’t want to trade on it. I am a private person; I think that’s important if you’re an actor.
‘But there’s a difference between privacy and secrecy, and I’m not a secretive person.
‘Really I just want to get on with my job, which is to pretend to be lots of different people. Simple as that.’
All Of Us Strangers will be released in US cinemas on December 22 while the UK release is set for January 26.
