What follows are some pictures (found in an interview about the development here) and a few ideas I got about it.. A video with some scenes of the labyrinth moving and shifting can be found here.
It all starts at an impressive door of magical enhanced stone:

To make it an entertaining experience for the players, it will need some sort of subsystem to make it work and produce some tension on the way. And it shouldn't be about not being able to open the door, but more about what ressources are needed to get there.
One of the missing pieces in D&D, for me at least, is the lack of rules for creating and manipulating (magic) environments. Sure, there are some connectors (how to create magic items, some spells, skills, etc.), but mostly it just gets waved away. How all those evil wizards are able to build the traps, doors, entire dungeons or creatures they have in their lair is just beyond the rule book (as far as I'm aware of).
How to manipulate matter
This idea is pretty vague right now, but I'll explore it further in another post. So far I'm thinking about giving Magic Users the possibility to sacrifice a spell slot to gain the ability to manipulate a certain kind of material to an extend related to the spell level used and how hard it is to work with the material. With racial modifications (it should be easy for dwarves to manipulate stone, for instance). Materials could be wood, leather, stone and metal (with some exotic variants for living matter and undead). Very experienced Magic Users should be able to manipulate more than one kind of material, but specialists working together should be an option, too. A somewhat different, but nonetheless very interesing approach to this is the Eberron class that James C. introduced a few days ago over at A Dungeon Master's Tale.
An ever shifting Megadungeon
After opening the magic door, the heroes enter the labyrinth. Here's a picture of it:
But I digress. What really blew my mind was when the dungeon in the movie started to change.

With the possibility to tinker with the moving parts of the dungeon (sabotage by the thief, magic manipulation by a specialist Magic User, maybe clerics can be involved, too), a whole new set of adventure opportunities arise. Preparation becomes a crucial necessity and that's what I was looking for.
That's it so far, the rest will follow. Here is another nice pic from the movie:
