They also reveal their favourite war movies of all time.
So... let us take a little look at the two leading men in the new WWI epic, 1917.
We've got Dean-Charles Chapman, perhaps best known for playing Tommen Baratheon in Game Of Thrones. But for those who didn't watch The Biggest TV Show Of All Time, you might also recognise him from the likes of Into The Badlands, Blinded By The Light, The Commuter, Before I Go To Sleep, or The King.
And we've also got George MacKay, perhaps best known for playing the eldest son in Captain Fantastic. But for those who haven't seen that family drama, you might also recognise him from the likes of How I Live Now, Pride, Marrowbone, 11.22.63, or Sunshine On Leith.
Together in their new movie, they're surrounded by some incredible heavy hitters in front of the camera - Colin Firth, Benedict Cumberbatch, Andrew Scott, and Mark Strong - and behind the camera, they've got Oscar-winning director Sam Mendes (American Beauty, Skyfall) and 14-time Oscar-nominated cinematographer Roger Deakins (Sicario, Blade Runner 2049).
So with all of that talent, you know you've got to bring your A-game, and that is exactly what they do here, pinning the entire ticking-clock thriller almost entirely to their performances.
Perhaps all of that pressure helped to add to their turns in the movie, and when JOE sat down with them in the run up to the movie's release, we had to ask which scenes were the toughest for them to film, especially considering the incredibly technical, single-take aspect of the project.
We also chat about their favourite war movies of all time, their opinions on Andrew "Hot Priest" Scott, and working alongside living legends like Mendes and Deakins.

Meanwhile, JOE was also lucky enough to chat to the movie's writer Krysty Wilson-Cairns (which you can watch here), as well as the movie's director Sam Mendes, who has just won the Golden Globe for Best Director (which you can watch here).
1917 lands in Irish cinemas on Friday 10 January, and you can watch the behind-the-scenes featurette on the movie right here:
