The 25-year-old British actress stars as deadly assassin Villanelle in the much-loved series, and her scenes see her murder people in various grotesque ways.
But in an interview with Entertainment Weekly, Jodie revealed it was actually a much more mundane thing that nearly claimed her life.
"It's a scene where she's (Villanelle's) eating some pasta in a very grotesque way," Jodie said. "She's trying to prove a point about something. She's playing it up, being her usual childish self, and the pasta was extremely dry. And it was extremely thick.

"I was shovelling it in, and then it just shot down my throat and then I was full-on choking. They must have it on camera - a medic came in and managed to get it out, but my life definitely flashed before me...".
"I just remember being opposite the other actor and looking at him, and he thought I was making a weird acting choice. So yeah, it's ruined pasta for me completely."
Jodie added that when she told her brother Charlie about the terrifying incident, he had a hilarious response.
"Oh. My. God! This is actually really triggering. I told my brother about it and he was like, 'I love this. Of all the things that could have killed Villanelle, it was a mouthful of pasta'," she laughed.
Jodie and Sandra Oh, who recently won the Golden Globe, SAG and Critics' Choice awards for her portrayal of MI5 officer Eve Polastri in the show, are both returning for the second season, set to premiere in the U.S. in April.
