Revealing mistake: In Episode 2 during the scene when the king's son is born, it appears that the baby has been born for less than a few minutes, but when he is held up it is plain to see that his navel has healed instead of being freshly cut As It Should Be after the birth. (00:31:50)

Queen Katherine: He will tire of you, like all the others.
Anne Boleyn: And what if he does not?
Question: Henry VIII was over 300 pounds through much of his reign. Why was Jonathan Rhys Myers not padded more realistically to portray him?
Answer: Although the series claimed to be historically accurate, there were many factual discrepancies throughout, including the extent of Henry's physical health and morbid obesity. As to why this was changed, the creators apparently felt they could better dramatize the story with a more physically fit and mobile Henry. In the real Henry VIII's later years, he was so incapacitated by weight and other maladies, that he literally had to be carried around by attendants.
Answer: While he was obese for much of his life, Henry VIII didn't gain significant weight until after the death of Jane Seymour when he fell into a deep depression and succumbed to the pain of a leg injury he obtained from a jousting accident. He should've been heavier but he wasn't obese for his whole life, especially during his younger years. He was known to be 210 pounds, standing at 6'2", and to have a 32" inch waist for much of his life.
