"My best memory is the cast dancing in the fitting room — seeing Meryl Streep, Nicole Kidman, James Corden, and Andrew Rannells just busting a move. We would always have them DJ, and we'd play music while they each did their fittings. It just brought me great joy to see the energy each one of them put into their part. Ariana DeBose would sing during her fitting, and it just gave me chills. We'd play Donna Summer, and she would just bust it — it was so amazing," Eyrich said.
