 The producers strongly considered casting multiple actresses in the  role of Lily, alternating different performers for each scenes  rendition. This had less to do with any artistic choice, and more to  do with the fact that they had such a difficult time deciding  between a plethora of different, highly talented actresses who  showed up to audition, each of whom had different strengths, and  performed completely different scenes with varying degrees of skill.  Ultimately, Talia Rubel was cast both for her exceptional acting  ability as well as the fact that she looked virtually identical to a  computerized sketch of what the director imagined the character of  Lily to look like.
