According to Entertainment Weekly, Julie Delpy (Before Sunset) is rumored to have a role in the film. It’s probably for the role of Sophie Nevue, the talented French cryptologist who accompanies Robert Langdon (Tom Hanks) in his journey to decipher the Da Vinci Code.
Due to pressure from the organization Opus Dei, which the novel portrays as being evil, EW also reveals that the filmmakers are considering changing the name of the cult to something else.
