Unfortunately these movie based rides never left the development stage, but I am still holding out hope that they will build an Atlantis: The Lost Empire attraction.
The Nightmare Before Christmas ride
Ride Description: Guests seated in flying coffins and would have embarked on a journey to help Jack Skellington "save Christmas." The ride would have been constructed right next to It's a Small World at Disneyland
Why It Wasn't Built: Reportedly, Tim Burton (who owns 50% of the rights to the characters) nixed the idea. But, elements from the ride are incorporated into the Haunted Mansion's annual Nightmare Before Christmas overlay.

Dick Tracy's Crime Stoppers
Ride Description: An interactive shooter ride that would have featured a car chase through the streets of 1930s Chicago.
Why It Wasn't Built: Disney cancelled the ride after Dick Tracy failed to perform as expected at the box office.
Mary Poppins ride
Ride Description: Originally planned for Fantasyland, the ride would have been built in a similar style to the Haunted Mansion.
Why It Wasn't Built: No reason has been given why it was canceled.

Baby Herman's Runaway Baby Buggy
Ride Description: Based on the Roger Rabbit short “Tummy Trouble,” the ride would have had a similar feel to Mr. Toad's Wild Ride.
Why It Wasn't Built: The economic problems caused by the failure of Disneyland Paris in the early '90s cancelled the project. But elements of the ride were incorporated into Roger Rabbit's Car Toon Spin.
