*At the beginning of the film when Mr. Incredible is in pursuit of some criminals, the map which he looks at features the names of streets surrounding Pixar studios.
*In this shot, ‘The Luxo Deli’ is a reference to Luxo Jr. (1986) and ‘Andy’s’ is a nod to Andy from Toy Story (1995).
*The Rock ‘Em, Sock ‘Em toys from Toy Story 2 (1999) appear in Bob’s office.
*A113 is referenced twice. The first is a room number which Mirage tells Bob to visit. The second is far more subtle; Elastigirl checks the monitor to find where Bob is being held and discovers that it is on Level A1, in cell 13.
*There’s a lot of controversy regarding whether or not the Pizza Planet truck appears in The Incredibles. Lee Unkrich, director of Toy Story 3 (2010) claims there isn’t one, but John Lasseter disagrees. According to Jim Hill Media, the Pizza Planet truck does appear during the finale when the camper van is driven at high speed through New York. However, it goes by so quickly that it’s only possible to see a vague blur. Anyway, here are the images that site provided and I’ll leave it up to you to make up your mind.
*During the final battle with the Omnidroid, Doc Hudson from Cars (2006) can be seen in the background.
*The two old men who comment after the battle are caricatures of legendary Disney animators Frank Thomas and Ollie Johnston. They even provide the voices!
