Video: In what is now the sixth instalment of a stunning and weirdly addictive series, the BBC has released 10 full hours of video shot during the filming of the Planet Earth II "Cities" episode.

Video: When shooting a documentary, the vast majority of what you film gets edited out of the final production. But instead of letting thousands of hours of breathtaking footage go to waste, the creators of Planet Earth II have re-purposed hundreds of breathtaking mountaintop shots into this 10-hour-long relaxation tool.

Video: Yeah, sure, replacing the noises that animals make with human screams is totally silly but, man, some of the edits of these scenes are really freaking good. Matt Amys took footage from Planet Earth II and then swapped out the audio with screams that are damn near perfect for each situation. Life is way funnier when animals sound like humans.

Video: The next time you get rejected, thank your lucky stars you're not a male widowbird, the poor creature who has to jump really high for a long time just to get a little bit of attention and, if all goes according to plan, some action.

The only thing attracting more attention than the US election right now is that harrowing Planet Earth II video showing a recently hatched iguana as it fends off an army of snakes. For those who can't get enough of this clip, BBC Earth has released some new footage of the encounter as it was being filmed.

The BBC's long-awaited Planet Earth II documentary series began airing in the UK over the weekend. It's the follow-up to the incredible original series, was filmed entirely in 4K, and is narrated by Sir David Attenborough. We finally know when and where you'll be able to watch Planet Earth II on Australian TV -- and you'll have to wait a while.

Video: Yesterday, the BBC made the dreams of every naturalist and David Attenborough fan come true when it broadcast the first episode of Planet Earth II, the sequel to the magnificent 2006 series.
