We’ve long suspected it for years, but Disney has finally made it official: each and every single Pixar film is set in the same universe.

In fact, moviemakers have been laying out clues (known to film buffs as ‘Easter eggs’) for years. Every single world they’ve created – from the medieval Scottish landscapes of Brave, to the futuristic world of Wall-E, right down to the teeny-tiny corridors of A Bug’s Life’s ant hill – is connected.

And Disney has now collected all those linked clips and collated them into one incredible video, which you can watch below.

Remember Boo, from Monsters Inc? She has a Nemo toy. And the boy sat in the dentist waiting room during Finding Nemo is reading an Incredibles comic.

The mural created by Merida and her mother in Brave finds its way into the world of Cars several hundred years later, while Buzz Lightyear can be seen running past a Flik toy from A Bug’s Life. And Riley, from Inside Out, is at the very same aquarium that Dory finds herself trapped in. And, and…

Well, you get the picture.

While some of the clips are clearly just for fun and simply show characters appearing in different guises (such as Arlo from The Good Dinosaur being a toy on the floor of the test bedroom in Monsters University), others definitely point to the stories having been set in the same universe at different times.

And perhaps the most poignant Easter egg of the latter type is that spotted in Wall-E, a dystopian film about humanity’s destructive effect on Planet Earth.

Set in 2805, it follows Wall-E, a lonely robot trash compactor charged with cleaning up the planet that humans contaminated and abandoned so many years ago. One day, however, he stumbles across a scooter. And, as Disney’s new video proves, this scooter is the very same one ridden by Skinner in Ratatouille – a film set in the 21^st century.

It’s an important message, and one which echoes the words uttered by David Attenborough in the final episode of Planet Earth 2.

“Now, over half of us live in an urban environment,” Attenborough stated. “My home, too, is here – in the city of London. Looking down on this great metropolis, the ingenuity with which we continue to reshape the surface of our planet is very striking. But it's also sobering. It reminds me of just how easy it is for us to lose our connection with the natural world.

“Yet, it's on this connection that the future of both humanity and the natural world will depend. And it is, surely, our responsibility to do everything within our power to create a planet that provides a home not just for us, but for all life on Earth.”

That’s right, we linked Attenborough and Pixar.

It remains to be seen whether Pixar will attempt to teach audiences another important lesson in their next movie, Coco, which is scheduled for release in November this year.

The film follows the adventures of Miguel, a little boy who lives in a Mexican village. Raised by shoemakers, he has secret aspirations of becoming a musician – only that proves to be difficult, as his family has banned music because they believe they’ve been cursed by it.

As the Rivera’s family history goes, Miguel’s great-great-grandfather abandoned his wife decades earlier to follow his own dreams of performing, leaving Imelda (Miguel’s great-great-grandmother) to take control as the matriarch of the now-thriving Rivera line and declare music dead to the family forever.

But, when Miguel learns he’s connected to his favourite singer of all time, the late Ernesto de la Cruz, he takes action – and, in doing so, accidentally enters the Land of the Dead.

In the beautiful underworld, it’s not long until Miguel encounters the souls of his own family, including Imelda. Together, they decide to track down De la Cruz himself, in a last-ditch bid to earn his family’s blessing to perform, but time is not on their side. Can Miguel return to the Land of the Living before time runs out?

Yep, we’re on board.
