The Other Boleyn Girl (2008)
Historians are divided over whether one or even two of Mary's children (sons) were in fact sired by the king or not, and it is noteworthy that he did recognize a bastard from an earlier dalliance (Henry FitzRoy, by mistress Elizabeth Blount).
It is not believed that Anne ever saw Mary again after her banishment back to the countryside. Mary eventually married a low-born soldier for live, and was immediately disowned by her family.
The length of time depicting Anne's reign of power and time with the King is SEVERELY foreshortened. She actually wielded a great deal of power and held Henry's affections for a much longer period of time than indicated in the film.
Also, historians are divided as to whether she actually did commit incest with her brother, or whether it was just a viable excuse conjured up by Henry and Woolsey, when a solid excuse was needed in order for Henry to be freed from Anne as his attentions waned. The two siblings were quite close, but whether they ever became more than brother & sister is highly contented among historians.
