The Incredibles was the first- and, to date, only- feature Pixar film to not have the pizza truck in it. We are happy to be proven wrong on this, so if you spot it, let us know. Otherwise, you will have to content yourself with two A-113’s…
A-113 in The Incredibles
The first is audio-only. When Mirage is touring Mr. Incredible around Syndrome’s lair, she mentions this as the meeting room number.
The second reference is infered. You get the A-113 when you combine the prison level where Mr. Incredible is held (Level A1) and his cell number (13).
Other Pixar Films Hidden In The Incredibles
When Lucius and Bob drive out of an alleyway on their way to rescue people from a fire, one building has a sign for “Andy’s (the boy from Toy Story), while across the screen is a second sign for the Luxo Deli.
In the climatic final battle, as Mr. Incredible battles the Omnidroid, we can see a preview of Doc Hudson from Cars.
