Sir David Attenborough again set a record with his spectacular nature documentary — Planet Earth II, as the debut episode of Planet Earth II has become the most-watched natural history documentary in more than 15 years.

Last week's episode has now nabbed 12.26 million views, absorbing 40.9 per cent of the television audience.

In the first episode, the entire nation was thrilled by the unbearable tension of watching baby iguanas flee a mass of racer snakes.

After BBC hired the Hollywood composer Hans Zimmer to compose a film-worthy soundtrack, the Attenborough show has already beaten Blue Planet in 2001, the first series of Planet Earth in 2006 and Frozen Planet in 2011.

Planet Earth II is currently achieved the highest performing title of 2016 so far across all television, following The Great British Bake Off, Britain's Got Talent and the final of Euro 2016.

The second episode of David Attenborough's Planet Earth II, which was dedicated to mountain dwellers like snow leopards, golden eagles etc., racked up to an average of 10.6 million viewers.

90-year-old Sir Attenborough is one of Britain's most beloved, well-known, and respected public figures. He has been working for the BBC for more than 60 years. The first "Planet Earth" series was broadcast in 2006. This week he picked up an Evening Standard award for his work in broadcasting.

The upcoming episode of Planet Earth II looks at jungle life in the next week.
