Spencer's Princess Diana is hung up on Anne Boleyn, King Henry VIII's second wife, who was famously beheaded over the king's claims of adultery and incest — claims historians believe were all false and a ploy to remove Boleyn as his wife so he could marry his third wife, Jane Seymour. There are obvious parallels between Diana and Anne Boleyn's lives (like marrying into the royal family only to be betrayed). However, there's no evidence to support the idea that Diana obsessed over the former queen of England. Instead, this connection seems to be born from the imagination of the film's writer Steven Knight.
