A tale of two sisters competing for the same king, The Other Boleyn Girl uses historical facts as window dressing for this work of fiction that is entertaining, if not wholly believable.  Anne Boleyn is the doe-eyed vixen ordered by her power-hungry uncle to bewitch King Henry VIII.  Her shy sister Mary has always been in Anne's shadow, so when the King picks Mary--the "other Boleyn girl"--as his mistress, Anne turns on her sister and schemes to become not only the King's consort, but his new queen.  Based on Philippa Gregory's bestselling novel of the same name, this film is rated PG-13.
