ABC's Dancing with the Stars recently announced a new twist for the upcoming season. The new season of the ABC hit television show will premiere with 16 celebrities, and pare them down with one particularly "brutal" elimination schedule.

DWTS executive producer Conrad Green recently spoke with Entertainment Tonight to explain the decision, and hint at what's in store for fans of the show.

"This is going to be our biggest-ever cast (...) We are going to start big, and then about halfway through, we are going to do three double eliminations back-to-back. The middle of the season is going to be brutal when half of our cast goes in three weeks," said Green.

Green explained to ET that there are 2 reason for so many competitors this season; they need to fill the two-hour primetime timeslot, and he feels it is important to change up the show from season to season.
