Reports suggest that the actress made a deal with Legendary Entertainment to be a major part of the feature film adaptations of Nancy Springer's novel series. Two of the books, The Case of the Missing Marquess, and The Case of the Cryptic Crinoline, were nominated for the Edgar Awards in 2007 and 2010 respectively.
