CBS: No casting twists for 'Brother 10'

LOS ANGELES, July 8 (UPI) -- The U.S. reality competition series "Big Brother" won't feature any casting twists in its 10th season, the show's executive producer said Tuesday.

"Big Brother 10" is to begin Sunday with original host Julie Chen back to preside over the competition. Following the premiere, the show will be broadcast Sundays, Tuesdays and Wednesdays.

"To celebrate 10 seasons of 'Big Brother' we are going 'old school' and returning to the original concept for the show -- a group of strangers living together in a house and battling it out for half a million dollars. All 13 house guests have no prior relationship -- they are not exes, nor secret couples," executive producer Allison Grodner said in a statement. "We are also excited to have the most diverse group we have ever assembled. They range in age from 22 to 75, come from all walks of life, and have distinct points of view. This should make for an unforgettable 'Big Brother' summer."

The show follows people living together in a house where they are taped 24 hours a day. One by one, the house guests will vote each other out of the house and, at the end of three months, the last remaining house guest will win the grand prize of $500,000.
