What is the point of all the public auditions if they just use a casting agency? I think the first few big brother's were just regular people who had no links to any fame and weren't members of any talent agencies. I could be wrong about that though?
Do you think the quality of housemate would be better if they didn't use people who had already signed up with some agency in a hope to become famous?
Don't get me wrong, I loved Ben as a housemate and also like Gina of course, but I have often heard people say that BB would be better if it was just 'regular' people who were not actively seeking fame as maybe a person who is a member of talent agency is looking to be famous.
