The 41-year-old actor is in fact British and was born in London
However, Damian claims that since he landed a starring role in the award-winning US TV show Homeland, many people have doubted his real accent.
“I think I just look a bit white-trash American. I have heard people say, ‘That guy’s English accent is so fake,’” he laughed to the latest issue of UK magazine Esquire.
Damian plays Sergeant Nicholas ‘Nick’ Brody in Homeland, a former prisoner of war who is hailed a hero on his return to America.
The actor feels honoured to be involved in such a successful show and has compared working on the series to making a music album.
“I feel very, very lucky Homeland is as good as it is and I am in some small way contributing to it,” he gushed. “It’s such a lovely bonus and surprise, it’s a bit like making a great album, a happy accident, when all these talents are pooled and fire on all cylinders. But when you go through that strange level of success, when something becomes part of the national conversation, then that becomes another thing. There are moments when it can feel a bit daunting, because you’re not longer working anonymously.”
Damian is married to British actress Helen McCrory. The pair tied the knot in 2007 and they have two children together.
Damian is more in love than ever with his wife - particularly since she landed a role as a politician in the latest Bond movie, Skyfall.
“I can say, without fear of contradiction, that I am married to a Bond girl. Whether we see her in a bikini or not, she is a girl and she is in a Bond movie,” he laughed.
