Craig may seem unflappable when he is playing the role of Dr Alistair Kingsley on Mercy Peak, but the trek into the foothills of the Himalayas has him hot and bothered.

He ascends higher than the height of New Zealand's own Mt Cook, but Sir Edmund Hilary mountaineering laurels are safely out of Craig's reach.
