Emily Blunt "Astonished by the Outrage" Over Joke About Regretting Becoming a U.S. Citizen

The 'Sicario' star also sheds a bit more light on how she did on her citizenship test.

Emily Blunt was one of many stars who fielded political questions in The Hollywood Reporter's video lounge at the Toronto Film Festival.

And when the Sicario star said that she felt she'd made "a terrible mistake" when she watched the first Republican debate after becoming an American citizen, it was just a joke.

But critics quickly pounced on her remark as unpatriotic, something Blunt says disappointed her.

"I was bummed," the actress told Howard Stern on his SiriusXM show on Wednesday. "I was sort of astonished by the outrage because it was meant completely as an innocuous joke. So I think I was more taken aback, so it did bum me out."

She added that she thinks her comments were "like catnip" to those who criticized what she said.

But she also revealed, for anyone doubting her commitment to the U.S., that after studying intensely for the test, she aced it.

"You have to get 6 out of 10 [questions] right and I got the first six right, so they stopped," Blunt told Stern of her test, revealing that questions included things like "Who's the head of the executive branch? Who's the vice president?"
