Eagle-eyed fans of Disney-Pixar's animated films have long wondered if the characters in "Cars," "Monsters, Inc.," "Finding Nemo" and other beloved Pixar flicks all lived in the same cinematic universe.
The clues, they believed, were in each film's Easter eggs, not-so-hidden nods to other films in the Pixar collection, which spans more than two decades, dating back to 1995's "Toy Story."
For example, a "Toy Story" Pizza Planet truck shows up in just about every film, as does the number A113.
Now, Disney has pretty much confirmed the fan theory by dropping an epic video on the official "Toy Story" Facebook page, revealing exactly how all the films are connected.
The two-and-a-half minute clip reveals both obvious and not-so-obvious Easter eggs in "Ratatouille," Inside Out," "Brave," "Finding Dory" and more.

Most fans know about easy-to-spot Easter eggs, like Boo handing Sully a plush toy resembling Nemo in "Monsters, Inc."
But did you ever notice Sully's likeness is carved into a piece of wood in "Brave"?
And a motorbike from "Ratatouille" lies in a pile of debris in "Wall.E"?
Or that Riley from "Inside Out" shows up among a group of kids at an aquarium in Pixar's latest, 2016's "Finding Dory"?
Soon we're seeing how "Brave" links back to "Cars," and "Cars" to "Toy Story 3," "Toy Story 3" to "Up" and on and on and on.
Watch the video above to see all the exciting Easter eggs for yourself!
