Hollywood actress Emily Blunt has spoken about having "to be someone else" to deal with a stutter.

The British star said when she was growing up a teacher suggested acting as a way of "removing me from me".

Emily told The Sunday Telegraph's Stella magazine: "It was the most intuitive thing, and he was right: the only way I could speak fluently was to be someone else."

The 31-year-old actress, who stars alongside Tom Cruise in new film Edge of Tomorrow, said of her stutter: "It alienates you in some ways if you have trouble communicating.

"It wasn't that I got bullied horribly about it, although kids definitely had a go sometimes.

"It comes back if I'm tired or stressed."

Emily also spoke warmly about her co-star Tom.

"We laughed a lot. That's the wonderful thing about Tom: he doesn't take himself that seriously and he is very self-effacing.

"He couldn't care less what people think about him - that's quite refreshing."
