The NZ version is not up to the same standard of mean Greg and Timid Alex because the kiwis are too nice but the AU version with the two Toms is a pretty good mirror of Greg and Alex. Many tasks are the same so it’s cool seeing more tries and different outcomes.
There was a US version. It was a bastard of a Taskmaster, slimmed down cast, no prize task, and only 30min long. At least Alex was on it, I watched one episode and had to stop. It was canceled after 1 season. I think the real format could have worked if they stuck to comedians.
