Does Pirates of the Caribbean: Curse of the Black Pearl counts?
You have to remember, to make something as fantastic like the Lord of the Rings is a long-term project. It started way back in 1998 with pre-production that includes turning a farmland into Hobbiton and let the transplanted vegetation grow for one year so as if to look like it has been there.
And let us not forget the D&D movie debacle. That pretty much set the entire Fantasy genre two step backward.
Personally, if someone were to do a Dragonlance film project, I think Margaret Weis and Tracy Hickman should get off their six and start documenting appendix notes, although they may not be as well-detailed and semi-organized as Tolkien. You see, the motivation for Tolkien is that he truly wants to create a mythology for England, so he goes into the project trying to build a sense of history into the Middle-Earth myth, despite the fact that he is a poor story writer.
So, I'm hoping that Margaret Weis and Tracy Hickman start writing about the languages of the Qualinesti and the Silvanesti, as well as the Draconic Speech used by the corrupt Draconians as well as the noble metallic dragons. Perhaps they could try and collect the other author's works contributing to the Dragonlance lore and make them fit together.
It has to be a lot of work for a fantasy film to do well in the box office.
