“If you love singing and being a bubbly personality then you love Glinda best in the first act,” Felthous says. “That’s when you get to sing ‘Popular.’ But the actresses who have played the part always love her best in Act 2. That’s when you really can be in the moment and, honestly, I’d rather sound bad than not be in the moment. When I played Nessa, they all used to call me the ‘snot-and-tears Nessa,’ but I think there always is something beautiful in watching someone just not look good at all. When you look awful, the audience knows exactly how you feel.”
