One contestant will also be "America's Player"

There will be plenty of drama in the "Big Brother" house this summer, if the CBS casting department has anything to say about it.

On Thursday (June 28) CBS announced that the big twist on this season of "Big Brother" is that some of the castmembers will be shocked to discover they're sharing cramped living quarters with rivals, enemies and antagonists.

The network hasn't revealed how many of the 14 guests will be surprised with people from their pasts, but that won't be the only twist.

One of the shut-ins has been selected as "America's Player." At the end of each episode, starting with Sunday, July 8, viewers will get to vote on an assignment for America's Player to complete. It may be a personal action, a strategic choice or a voting decision. America's Player can't tell any of the other contestants that they're acting on the whims on online voters and America's Player can be voted off at any time just like any other player. But if America's Player succeeds at giving the people what they want, there will be financial rewards.

In general, this season's cast looks much more like "The Real World" than "Big Brother." Of the 14 castmembers, all but three are in their 20s and none are older than 44-year-old Dick, a bar manager from Los Angeles. The cast includes the usual assortment of waitresses, students and receptionists. There's also 25-year-old Nick, allegedly a former professional football player.
