I was on the last series Richard O'Brien did. A great 2 days! He really is a good laugh. Loads of memories. One of the girls falling in the Aztec river. Thats OK though it was hot, wasn't it? NO. It was filmed in a hangar at North Weald airfield in November and the day before they had to break ice off the Aztec river!! As to catching the money, it looks easy on TV. What they don't show you is that the dome is lit with orange light. Under that light the silver paper looks gold, so it is almost impossible to tell the difference. BTW, we had one team member locked in and we didn't get enough gold, but it was great fun.
