I think the answer you're looking for is Audrey Tatou, who played Sophie in the movie. She also starred in Amelie.
Audry Tatou was one your looking for who played as Sophie Neveu.
French film actress Audry Tatou.
The female character in the movie (same title as the original book) is Agent Audrey Tatou as Sophie Neveu, who starred as a French National Police crytographer, who studied at the Royal Holloway, University of London Information Security Group.
The female character is the holy grail herself. She is actually the only living decendant of Jesus Christ. There fore she is the only proof that Jesus was merely human.
