(Miss Scarlett also does much of the movie in minimal makeup and as such she'd look right at home somewhere in my mother's family tree, who are all Norskis. Gee I hope Ms Scarlett wouldn't take offense ≤}B^).
The movie does take liberties with historical fact, although probably not as severely as, say, Amadeus.
I personally didn’t really think that Portman was up to the role of Anne Boleyn. I think Natalie Dormer from the series “The Tudors” was much better.
Although for historical accuracy both the tudors and The Other Boleyn girl are awful, however I’d have to give the nod to The Tudors as well. It gets some of the historical facts correctly, such as King Francis telling Henry regarding Mary Boleyn: “I call her my English mare because I ride her so often.” Whereas in the movie she was portrayed as a innocent up to her marriage to William Carey, when that was not the case.
Because her mother is Jewish, I suppose that Scarlet Johansson could also be considered Jewish. As I understand it, if the mother is Jewish so is the child.
