Hunger Games - The Movie

Every time a book I've enjoyed is made into a film, my first struggle is to reconcile my mental image of the characters with the appearance of the cast members.  Jennifer Lawrence was chosen to play Katniss.  My first reaction is she is a little older than what I pictured - more sophisticated.  It remains to be seen how they'll be able to transform this red-carpet beauty into the gritty heroine who plays The Hunger Game.
