Hi, I'm new.
How about this: a long series of 8 movies, so that most of the best bits of the Silmarillion can be portrayed?
MIDDLE EARTH: THE FIRST AGE
1. The Beginning
can start with Illuvatar & the Creation as a prologue, including Melkor and later the awakening of the elves.
also, the life of the Noldor in Valinor, the Silmarils, the oath of Feanor, etc, ending with the coming of the Noldor to Beleriand, the death of Feanor, and the elves spreading and founding their kingdoms

2. The War of the Jewels
all the main battles of the war of the jewels in detail, the coming of men, introducing Hurin & Huor, and Barahir father of Beren

3. Beren & Luthien
starting with the introduction of Thingol & Melian & Luthien, and separately the death of Barahir & the adventures of Beren in the north, then the tale of Beren & Luthien in detail, ending with their return to Beleriand

4. The Children of Hurin
everything from the birth of Turin to his death, based on the Silmarillion and the version in Unfinished Tales, including the Fall of Nargothrond

5. Gondolin
the founding of Gondolin, including the tale of Aredhel, Eol, and Maeglin, and also the coming of Tuor to Gondolin, ending with his first meeting with Idril

6. The Ruin of Doriath
the tale of the ruin of Doriath and the Nauglafring based on both the Silmarillion and the version in The Book of Lost Tales 2, ending with the escape of Elwing and her growing up in the Havens

7. The Fall of Gondolin
This has to be my favourite one.
based mainly on the complete version in the Book of Lost Tales 2, but with adjustments as it is a very early version, starting with the wedding of Tuor & Idril, the birth & childhood of Earendil, the capture & treachery of Maeglin, then the Fall of the City in detail as it is in the Book of Lost Tales 2, ending with the escape of the Exiles, the duel of Glorfindel & the Balrog, and finally the coming of the exiles to the Sea and the meeting of Earendil and Elwing

8. The Voyage of Earendil
starting with Earendil & Elwing, including the voyage of Tuor & Idril, the various voyages of Earendil, the attack of the Sons of Feanor, the childhood of Elrond and Elros, the final voyage of Earendil with Elwing to Valinor, and finally the War of Wrath and what happens to all the remaining characters.

It's only a dream, I know its practically impossible, but it would be sooooo awsome to see something like this
