Just one year ago, young Isabelle Allen was acting in a school play (as a boy, no less). Today, shes the featured co-star of Hugh Jackman, Russell Crowe and Anne Hathaway in director Tom Hoopers big-screen adaptation of one of the longest-running musical in history, "Les Miserables." The ten-year-old Allen plays the younger version of Cosette, the illegitimate daughter of factory worker turned prostitute Fantine (Hathaway) who eventually grows up to look like Amanda Seyfried. You know that little girl on pretty much every "Les Mis" poster ever -- including the one for the film? Thats Cosette.
