From a disgraced politician to an actor best known for having been married to Shannen Doherty, this season's cast of Dancing with the Stars isn't just the largest yet (16 contestants), it's also the most random.

Speaking on the new set of Q-list celebrities that will take the floor this fall on ABC, Dancing with the Stars executive producer Conrad Green said:

“When we increase the cast we find it makes the competition more interesting. It was about trying to make it as big as possible and try to get that sense of fun and excitement and real character come through on the show.”

Will the plan be successful? Viewers will find out when season nine premieres on September 21. Here's a look at who will be competing for the crystal ball trophy:
