Eagle-eyed fans of Jodie Comer, the star of Killing Eve and Help, have noticed something about the way she behaves in interviews with the British media as opposed to those in the USA. See if you can spot what it is in the below video.
It is - of course - her accent.
The 28-year-old actor was born in Liverpool, and therefore has quite a strong Scouse accent.
However, whenever she gives interviews across the pond she seems to dial it back quite a bit, so that they can properly understand her.
It's a sad fact of life that many people struggle to pick out what folks with strong accents are saying, and that seems to count doubly for Scousers.
Still, Comer has clearly recognised this and decided to adopt a lighter way of speaking to avoid the potential for being misunderstood, or worse, subtitled.
Anyway, whilst she's clearly comfortable toning down her actual voice in order to make herself understood, you probably shouldn't go around asking her to do the voice of one of her most famous characters on command.
Comer played the role of Russian assassin Villanelle - or Oksana Astankova - in Killing Eve, and she recently revealed how she hates being asked to perform the accent on command as it makes her 'toes curl up'.
Speaking to Time Out, Comer explained: "Sometimes I get asked to do it if I'm out in a bar and someone's had a couple of drinks.
"My insides just go: "Urghhh" and my toes curl up. So no, I never get that one out - only when I'm on set and they say action."
She also told the publication about how she came to be able to perform so many different accents, having learned from watching telly with her dad.
She said: "Anything on the television that had some sort of regional accent, whether it was Cilla Black or a KFC advert. Me and my dad would always mimic them, purely just to make each other laugh.
"But I think that made me a bit fearless, so then when I was going to auditions and there was an accent on it that wasn't my own, I wasn't intimidated."
As for her own accent, Comer has shocked a few of her co-stars over the years by revealing her own.
Matt Damon and Ben Affleck, alongside whom Comer stars in the forthcoming The Last Duel were amongst those to be unaware of her real voice.
She explained: "It's funny because we were in Venice recently and Ben was like: 'I think this is the first time I've actually heard you speak properly in your own voice...'"
