It's a fan-made movie, and not just one of those cheesy "put together some random scenes and stick it on youtube" things, either.
They have a good crew with them, some people who worked on "Avatar" and "Narnia: The Lion, the Witch and the Wardrobe" are working on this. You can also look here..

There's another movie on the go, too. (Also fan-made.) You may or may not have heard of it; Operation Chastity.
