The pilot starred Michelle Ryan, Miguel Ferrer, Molly Price, Will Yun Lee, and Mae Whitman. In June 2007, "TV Guide" reported that Mae Whitman was being replaced in the role of Jaime's sister. An NBC spokesperson confirmed this, stating, "The decision was purely creatively driven. It is very common to change storylines, characters, actors after the initial pilot is shot." The character, who was originally deaf, had her hearing restored when requested by an NBC executive. Lucy Hale was later cast as Whitman's replacement in July 2007.
