Planet Earth 2 was shot in 40 different countries, with crew making 117 film trips, 2,089 total shooting days or over 5.7 years non-stop.
This is the first BBC series to be produced in Ultra-high-definition 4k technology.
During filming on Zavodovski Island in South Sandwich, one of the camera was doused during a storm and it would take 7 days by boat to have it replaced. The crew had to warm it up by using heat packs, sleeping with it and even above the stove to dry it.
Close to 10 million people tuned in to the first episode of Planet Earth 2 shown on BBC One.
Hans Zimmer composed the score for the new series and composed the main theme. He is famous for creating music for the Dark Knight trilogy, Inception and Gladiator.
