This week we find out what happens when an 'unknown' actor is cast in a leading role for their first time on Broadway. First up, Margo Seibert, who was put through 9 auditions--9!!--before landing the coveted role of Adrian in last season's "Rocky." Then we talk to Amber Iman who takes us through her journey of being cast as the legendary Nina Simone in the short lived "Soul Doctor."
