Seven minutes into Summer Phoenix's audition for "Esther Kahn" -- about an 1890s Jew who wants to become an actress -- director Arnaud Desplechin hastily left the room. "The casting directors were like, 'OK, thank you,'" recalls the exuberant, almond-eyed Phoenix, sister to actors Joaquin and the late River. "I walked away, but then I just started sobbing and I ran back up the stairs. I cried, 'Esther Kahn' is the role I've been waiting for. This can't be my last chance.'"
