THE OTHER BOLEYN GIRL: Natalie Portman, Scarlett Johansson, Eric Bana, Rue McClanahan (Directed by Justin Chadwick; Written by Peter Morgan; Sony) Quick! Who was Mary Boleyn? You know, of course. She was the younger sister of Anne Boleyn, the regal mate of England’s King Henry VIII who literally lost her head in 1536 as a result of trumped-up charges that she was guilty of adultery, incest and witchcraft. Mary, who was married to William Carey at the ripe old age of 12, was by no means a stranger to the lascivious king herself, having served as his infamous mistress--and possibly the mother of his son--before Anne popped onto the scene. Why should you care about all this ancient history? Because Anne and Mary are being played by Natalie Portman and Scarlett Johansson (above), respectively, in this adaptation of Phillipa Gregory’s fact-based novel. Eric Bana will undoubtedly have a romp as horny Henry. And if you’re a pushover for the royals, you must also check out "Elizabeth: The Golden Age," starring Cate Blanchette in the tale of the monarch whose mom was Anne Boleyn, and "Queen," starring Helen Mirren as the lady who currently sits upon the British throne. “Queen,” written by “The Other Boleyn Girl” screenwriter Peter Morgan, opens the New York Film Festival on September 29, prior to its October release, and “Elizabeth: The Golden Age” will come marching in some time next December.
