 When King Tutankhamens tomb was found on November 4, 1922, the  person in charge was Lord George Herbert, Earl of Carnarvon. Along  with him was his daughter, Lady Evelyn. Rachel Weisz (qv)s  character is named Evelyn Carnahan. Originally, her character was  meant to be Evelyn Carnarvon. She and her brother were to be the  children of the "cursed" Lord Herbert. The only evidence of this  left in the film is in the line where Evelyn tells OConnell that  her father was a "very, very famous explorer". The Mummy  novelization goes into a bit more detail on her back story.
