On Wednesday the BBC’s new flagship series, Frozen Planet starts, taking us to the ends of the Earth; the Arctic and Antarctic, and the dramatic desolation of these harsh environments.
When I met Sir David Attenborough earlier this year, we talked about the making of the series and he professed admiration for the cameramen who risked their lives diving under the thick ice in subzero temperatures to capture some of these incredible shots.
The series also features an incredible chase as wolves hunt down bison in temperatures of -50 degrees and winds of up to 100mph. Whilst the wildlife might be used to it…here the crew describe how they had to adapt to their new environment to get this stunning footage.
