Damian Lewis is a "sponge" when it comes to learning accents.
The British actor has perfected a US voice for his role in television drama Homeland.
The 41-year-old says speaking in an American way when he is in Los Angeles helps him stay in character.
"I am a bit of a sponge like that," he explained to British magazine OK!
"My problem is that I am not sure how to categorise these events - I come to LA, I drink a lot of whisky, I see my friends, so I feel like I am kind of on holiday, but I also realise that I am in the workplace here as well. When I work on set, I wake up in an American accent, and I don't come out of my American accent until someone shouts: 'Wrap!'"
Homeland was on a winning streak at the Emmys this year, collecting awards for both Outstanding Drama Series and Outstanding Writing for a Drama Series.
Damian's co-star Claire Danes received the award for Outstanding Lead Actress in a Drama Series, while Damian himself won Outstanding Lead Actor.
"It's unthinkable. I have never been in this position before," he exclaimed.
"I suppose we were popular right off the bat - it was kind of amazing how quickly we struck a chord with people. I am absolutely thrilled."
