The Australian version of this show was hilariously bad. I think most of the gladiators are now selling used cars for a
living.
They're doing a new Australian version too. Apparently Anthony Koutafides and Tatiana Gregoriava are in it. I'm not sure if they are contestants or gladiators, though. No doubt it will be shit.
audiophileguy makes a good point though. It seems more like a reality show with the way the contestants interact with the hosts.
