“I don’t like America and I didn’t want to be in Georgia for four months,” Miriam continued. “So I just said, ‘well, I want a million pounds’ [which would be about $1.2 million in U.S. dollars] and they said, ‘you can have half a million’, and I said, ‘no, I don’t want to do it’, so it just stopped. Really it’s a story about my own greed rather than anything else.”

In a recent interview, Miriam shared why she’s “worried” about certain Harry Potter fans.

Oh Miriam! will be released on September 12.
