Sir David Attenborough has teased some details of his next BBC documentary series, and if it's anything like... well, anything Sir David Attenborough has ever done, then we are in for a treat.

His new project will follow different creatures across a three year time period, reports The Mirror.

"The BBC Natural History Unit has started following families of animals – cave hunting dogs, lions, chimpanzees," the veteran broadcaster said.

"We don't know what is going to happen but whatever does, we will be there to show it to you.

"I am not going to go into detail but I can tell you there will be some fairly dark moments and we wont tidy it up.

"This is a new concept and I am privileged to have been be asked to write some of the commentary."

The recent Blue Planet II similarly refused to shy away from uncomfortable moments. The show's coverage of what plastic waste is doing to our oceans or how humans have damaged the coral reefs may not have made for easy viewing, but they are important topics to shed a light on.

Attenborough was speaking at BAFTA masterclass in London, and added that he's glad that politicians are now taking notice of the condition of our oceans.

"If we have woken up, it is only the beginning," he added. "We have made a real mess of the world. We really, really have.

"Something has to be done about it. I am grateful politicians are taking notice. This is serious."

The show's producer Orla Doherty told Digital Spy that a third series of Blue Planet is definitely possible, and with 70% of the Earth being covered in water it's not like there are a shortage of things for Attenborough to narrate in that soothing voice.
