Does King Charles relate to Sir Christopher Nolan's Joker?

British-American filmmaker Christopher Nolan received a knighthood from King Charles for services to film.

His wife and film producer Emma Thomas also  received a damehood, the female equivalent of a knighthood.

Nolan's "Oppenheimer", a blockbuster biopic about the race to build the first atomic bomb, claimed seven Academy Awards earlier earlier this year, including the best picture trophy and Nolan's first best director Academy Award. 

His career includes other highly regarded films such as "Interstellar," "Inception", "Dunkirk" and the Batman trilogy.

The official Instagram account of the Royal Family shared multiple pictures from Nolan's movies including the Dark Knight.

The royals chose Joker's picture from the Dark Knight for the Instagram post  after the ceremony. 

Those who have seen the movies know that almost every character gets a memorable quote in the Dark Knight trilogy.

It's not clear who picked Joker's picture for the royal family's Instagram post but fans are wondering whether the King who honored Nolan relate himself to either Batman or Joker.
