Look at this, I found:

Reg Heathcote:http://imdb.com/name/nm2934088/

Patricia Quinn: http://imdb.com/name/nm2926787/

Natasha Hall:http://imdb.com/title/tt1185884/

Katy Walsh: http://imdb.com/name/nm2926743/

Why on earth are they listed on a movie database?!

It does TV programmes aswell.

Yes, but they list actors and members of the crew etc... I think listing game show contestants is a bit odd.

I think their policy is that if someone is listed in the end credits of something, they are eligible for a page of their own. So thanks to Alfie's game listing all of 2005 and 2006's contestants, and Glen's listing 2007's, that's the majority of all of them - but that does mean that the 2008 contestants mentioned actually should not have their page, as they've never been credited!

Here's mine, by the way
