I will be the first to admit I was terrified when they cast Ariana Grande as Glinda. I thought it was just stunt casting for pop fans. But oh my god, I was wrong. She completely disappears into the role. Her comedic timing, the operatic vocals, the chemistry with Cynthia Erivo—it is perfection. She isn't playing a pop star; she is playing a theater icon. If she doesn't get at least a Golden Globe nomination for 'Popular,' the system is rigged. She was born to play this role
