There was a documentary called Big Brother Small World mind you, although it wasn't really a follow-up programme.

It looked at different Big Brothers around the world, including the UK.

Several BB2 housemates were interviewed on it: Helen, Paul, Brian, Amma and Stuart.

I've done a video of some of these clips. You can get it here:

Thanks again, James! You are a treasure!
