In this period potboiler, Natalie Portman and Scarlett Johansson star as history's famous Boleyn sisters, who vie for the courtly favor (and royally hot bod) of Eric Bana's King Henry VIII. Adapted by Peter Morgan (The Queen) from the best-selling novel, Boleyn has a pedigree worthy of its inspiration. As if the mere thought of a corseted catfight between these two weren't enough to make some lose their heads.
