If you didn’t know, Sarah is starring in a production of The Picture of Dorian Gray right now. The show opened on Broadway in March after transferring to NYC from London’s West End. Sarah — who stars as all 26 characters — recently sat down with the New Yorker to chat about her process for the super challenging role. Or roles, plural.
