Although this is not cave related, I am posting it as Bear Grylls has been mentioned in my blog.
In May 2016 it was announced that ITV has cancelled Bear Grylls TV show, Mission Survive, after two series. See The Guardian report, 31 May. The reasons are due to a fall in ratings.
As far as I know, none of the episodes were filmed in caves.
Bear Grylls has received many negative comments from international cavers in the past due to his reckless / dangerous attitudes to caving - see labels on the column to the right.
