When Anne is standing on the platform saying her last words, the swordsman is wearing a bomber-type jacket. When he picks up his sword, he's wearing a leather vest.
When Anne and King Henry are arguing and Mary picks up Elizabeth to calm her, Mary's hair changes from being braided to straight down and back.
At the end of the film, after Mary goes to her mother to take Elizabeth, she switches from carrying the child laying in her arms in the shots from the front to carrying her on her hip in the shots from behind.
The film implies that Mary raised her niece Elizabeth. As royalty, Elizabeth had her own household. Margaret Bryon cared for her until she was four, then Kat Ashley took over her upbringing and education.
In the film, Mary Boleyn's first child is a boy. In reality, her first child was a girl, Catherine. Henry was born several years later.
The film refers to Mary is as the younger sister, but most historians believe she was the older girl. She was born around 1499, and Anne was born between 1501 and 1507. The book that the film is based on was written with Mary as the younger sister.
Elizabeth was not an infant at the time of Anne's execution, she was almost 3.
Mary asks Henry for a glass of water when she is first summoned to his bed. In the Tudor period, people didn't drink water because it was too dirty.
Written at the very end of the credits is the message: "This is a work of fiction. The characters, incidents, and locations portrayed and the names herein are fictitious, and any similarity to or identification with the location, name, character or history of any person, product or entity is entirely coincidental and unintentional." However the novel and film are based on the true stories of Anne Boleyn and Henry VIII with real people, historical events and locations that are also factual.

One exterior shot shows Penshurst Place as Anne Boleyn's family home. She actually grew up at Hever Castle in Kent.
Henry tells Anne that she is 'much changed' after her stay with the French queen. However, he says this in reaction to Anne acting bold, outspoken, flirtatious and calculating. She already acted precisely the same way with Henry before her exile, and he was only averse to her because of the hunting accident that she caused, rather than due to her personality. His sudden attraction to her makes little sense when she didn't act any differently towards him.
