You Probably Thought These 15 Actors Were American — Actually, They're Just Really Good at Accents

When House hit US TV screens in 2004, a large number of people had no idea that the lead actor wasn't American. In fact, it's reported that the show's executive producer Bryan Singer was so convinced by his accent, he said "See, this is what I want: an American guy," not realizing Hugh was a Brit who'd been famous in his native UK for decades.

Though his natural accent is more familiar now thanks to his work in high-profile shows like The Night Manager (for which he won a Golden Globe in 2018), those with a passion for British comedy will have recognized him instantly from his work in iconic shows like Blackadder in the 1980s. He also had a memorable cameo in a 1998 episode of Friends, when he berated Rachel on a flight.
