The making of an adventurous documentary like Deadly 60 is an adventure in itself, even if most of the time is spent waiting and searching, preferably with local guides or other experts, yet often even in vain. The tricks of the trade include safety measures, as for climbing, and getting acquainted in advance with dangerous animals, such as 'domesticated' hippo Jessica. Yet surprises always lurk, especially with wild animals. Biotopes themselves can be pretty uncomfortable, e.g. stinking, bugs-infested, spooky and/or dangerous, especially for team-members with phobias, such as deep caves, not to mention the elements. Sometimes animals just won't 'perform'.
