Comer rose to prominence following her dazzling portrayal of assassin Villanelle in Killing Eve, in which she effortlessly flicks between all sorts of accents, including Russian, French and Scottish.
The 28-year-old was so utterly convincing that viewers were left without the foggiest clue where she was actually from, with the discovery that she's from Liverpool coming as a huge surprise to many.
Now, none other than Ben Affleck has become the latest person to be shocked by this realisation.
The pair star alongside Matt Damon and Adam Driver in Ridley Scott's upcoming historical drama, The Last Duel, which is based on the true story behind the last legally sanctioned duel in French history.
Comer plays Marguerite de Carrouges - the wife of knight Jean de Carrouges (Damon) - and clearly, she didn't adopt her scouse accent for the part; in fact, Affleck didn't hear it properly until the movie's premiere at Venice Film Festival.
Speaking to LADbible, Comer said: "It's funny because we were in Venice last week, and I think that was the first time Ben heard me solidly speaking in my own voice.
"And he was like, 'Whoa, hang on a minute?!'
"So that was funny, but I think people generally do know that I'm from Liverpool now... I think?"
The Last Duel hinges on Marguerite's claim that she was raped by Jacques Le Gris (Driver), a one-time friend of Jean's.
The film is told in three parts depicting the respective versions of events of Marguerite, Jean and Jacques, culminating in a fight to the death to determine their fates.
Comer said it was a 'dream come true' to work with four-time Oscar-nominated director Scott, who was determined to work with Comer after admiring her performance in Killing Eve.

Speaking to LADbible, 83-year-old Scott said: "I've seen a lot of Jodie because I was one of the biggest fans of the show Killing Eve through three series.
"As it evolved, when I got into Russia, I was blown away by the Russian stuff. And so I just wanted to work with her, I wanted to find the opportunity to work with her.
"And so when Matt [Damon] said, 'I've got this thing about the last duel, we need to find a victim who is a woman at the centre of the story,' I go, 'So, the first person I'd call would be Jodie.'"
The Last Duel is out on Friday (15 October).
