A more detailed, text version is below

This version gives a more detailed look at what takes place in the programme
Selected material:
Longest continually erupting volcano, lasting over a century (when the series was produced)

Attenborough almost at the start of the programme (after some 2 minutes) talks about the lava lake Erta Ale as “the longest continually erupting volcano on the planet, a lake of lava that has been molten for over a hundred years.” Nevertheless he, a few minutes later, claims all the Ethiopian volcanoes are dormant, introducing the Andes as active (not showing any such activity). Strange inconsistency from an otherwise impeccable production.
A snow avalanche is always a very dramatic event

The above snapshots are taken with approximately 10 seconds interval (13’25-13’56)

One of the rarest and most majestic of wild animals

These are so hard to film, and this was actually a first for a decent sequence – a failed attempt at a hunt . . and then a successful one – not just a few seconds of practically nothing

From the ‘making of’ part of the programme (55′).
These sequences deserved a separate place in the ‘making of’ of how they actually managed to film those sequences. During the ‘making of’ the team managed to capture a magnificent shot of a snow leopard that almost feels like ‘posing’ for them. Obviously it is something more natural, like stalking a prey.
