For Emily Blunt, acting has led to a career she loves and a 7-year marriage to fellow actor John Krasinski, 38, but at a young age it also helped her deal with a stutter that she still has today.

Blunt says as a young girl she would often talk in “a lot of funny voices because I could speak more fluently if I didn’t sound like me.” Then, at age 12, a teacher overheard her doing different impressions and suggested she try out for the class play. “He said, ‘I think you are funny, and you should do it. And have you ever thought about doing it in a different voice?’” she tells PEOPLE’s Editor-in-Chief Jess Cagle in the latest episode of The Jess Cagle Interview (streaming now on People TV).

The London-born actress, 35, who is currently staring with Krasinski in the horror thriller he directed, A Quiet Place, in theaters Friday, and said that being part of her school production led to her love of theater.

And while the acting helped with her stutter, it didn’t get rid of it entirely. “It still comes back and flares if I’m really tired, or when I was pregnant it was really prominent again,” the mom to Hazel, 4, and Violet, 21 months explains. “It runs in my family. I had an uncle, cousin, grandfather who stuttered. It’s nothing to do with anxiety. It’s just a kind of brain-synapse thing that happens to people who are genetically predisposed to have it. The worst is having it at 12, 13.”
