Heel leuke chat weer inderdaad ::bravo::Gilles said that luckily, there were very few last minute changes this season. For the biggest improvisation he had to go back to the finals in South-Africa:
<Gilles> Normally the finalists went there for a hot air balloon ride, but the weather was too hot. That was replaced by a helicopter, and that in one way or another inspired us to bring back the famous push buttons from the beginning of the series and still make a little psychological game with it.
<Gilles> What I thought was beautiful then.
<Gilles> And we have been spared quite a bit this season!
I have read the whole chat log and I was quite thrilled when I saw my own question there, thank you very much guys for asking my question to Gilles!! I love how an improvisation by the production team still involves renting a helicopter
Also once again thank you to the organizers of this chat! It was a really fun read and it's really nice knowing some extra facts regarding the show.
