2003 BBC production of The Other Boleyn Girl and the 2008 film with Natalie Portman depict the two attempting but not committing incest. None of the sources Gregory listed in her bibliography questions Anne Boleyn's innocence. Gregory used two biographies of Anne, one by the American historian Retha Warnicke and another source by Marie-Louise Bruce (1972). Both these writers insisted that Anne was innocent, as did books by David Loades, Alison Weir, and Lacey Baldwin Smith that Gregory had used when researching the story. There is no evidence supporting Gregory's assertion that Anne had three miscarriages. Gregory ignores the argument that part of the reason Anne was executed was because of her political and religious leanings, which her brother shared and supported. Adaptations The Other Boleyn Girl (2003), telefilm directed by Philippa Lowthorpe A 90-minute television drama based on the novel was broadcast by the BBC in 2003. It had a relatively low production budget of £750,000 and was filmed using modern camera techniques, with much of the script improvised. Jodhi May played Anne Boleyn, Natascha McElhone played Mary, Steven Mackintosh played George, Jared Harris played Henry VIII, and Philip Glenister played Stafford. It received mixed reviews. The Other Boleyn Girl (2008), film directed by Justin Chadwick A 2008 feature film adaptation starred Scarlett Johansson as Mary, Natalie Portman as Anne, Jim Sturgess as George, Eric Bana as Henry VIII and Eddie Redmayne as Stafford. In Translating Henry to the Screen, a bonus feature on the DVD release of the film, screenwriter Peter Morgan discusses the dilemma he faced in adapting Philippa Gregory's 600-plus-page novel for the screen. He ultimately decided to use it merely as a broad guideline for his script, which Gregory felt perfectly captured the essence of her book, although many plot elements were eliminated, diminished, or changed. Among the more notable deviations in the film, Mary's marriage to William Stafford, a major part of the book, is mentioned only in a note just before the closing credits, there is no mention of Anne's "stealing" Mary's son to keep a grip on the king's favour (there was a scene designed to vaguely cover that, but it was cut from the film), Anne becomes pregnant with Elizabeth after being raped by Henry, Anne and George decide against committing incest, Mary adopts Elizabeth at the end of the film. In addition to this, the character of Elizabeth Boleyn is
