Keira Knightley learns American accent for new film

English actress Keira Knightley has learnt American accent for new release 'Jack Ryan: Shadow Recruit'.
The 28-year-old 'Pirates of Caribbean' star said that she had "a lot of fun" learning the accent and it was easier for her because she was surrounded by an American cast, reported Contactmusic.
"I got a dialogue coach. It was a lot of fun. I was lucky being surrounded by a lot of American actors that helps," she said.
Producer Lorenzo di Bonaventura, complemented her "impeccable accent" and that it was quite a challenge for her.
"She seems so quintessentially English, so the idea of her playing an American, I think that was a bit of a challenge in terms of what interested her. When you see the movie, it's the most impeccable accent," Bonaventura said.
