Just 10 INTERESTING people. People that are over 25, people that have actually experienced some real life not just the 'sample' of life that you get until your around 18/19 when your still sheltered by your parents.
If the Big Brother producers aren't capable of that then why not really go down the twists route. Not the pathetic boring 'we have another house' style twists that they think are amazingly clever. (They're not.) Pretend there's been a huge life changing event outside the house, drip feed the housemates news of bombs or a mass pandemic really fuck with their minds.
For a while I though this would make an excellent book, so right now I'm really pissed off that someone has beaten me to it.... but when I discovered that someone to be Charlie Brooker the hatred ceased and now I just can't wait to see the results.
Big Brother + Zombie apocalypse x Charlie Brooker = awesome, it might just even top Shaun Of The Dead...
