Mary Murphy and Nigel Lythgoe

It's that time again! So You Think You Can Dance premieres Thursday, May 21 (8 pm/ET, Fox) with a new crop of aspiring talent. Judges Mary Murphy and Nigel Lythgoe stopped by to chat with Matt Mitovich about what's new this season — including new styles from South Africa and Australia — and what they won't touch. Plus, Mary dishes on which audition city had the most beautiful pool of hopefuls, and which over-the-top auditioner is back again.
