Celebrity Circus Update:

The cast, which includes Christopher Knight, will compete in fifteen Celebrity Circus challenges: walking the tight wire; juggling or twirling fire knives; a gymnastics routine with the flying cube; climbing the Spanish web; being shot 60-feet out of a human catapult; performing acrobatics on the wheel of death; the trapeze bungee act; an aerial fabric routine; performing in the German wheel; performing acrobatics on the aerial hoop; swinging from the ceiling while performing complex moves; and a hand balancing act.
The celebrities will be aided by "top experts" in the circus world who specialize in the aforementioned acts and also trained with the participants for eight weeks leading up to the competition. In addition, the experts will also join the participants on stage during their performances to create a "rich, multidimensional act," according to NBC.

Following each performance the celebrity participants will be judged by Celebrity Circus' yet-to-be-announced judging panel, which will consist of "experts from the circus world."

However it will be home viewers votes cast following each episode that will determine which celebrity is sent packing each week and who ultimately wins.
