I think we need at least four movies:
-
The Fall of the Noldor: from "as early as is reasonable" to somewhere between the rising of the sun and the establishment of the realms of the Noldor
-
Beren and Lúthien. Put the Dagor Bragollach in the prologue.
-
The Children of Húrin. Put the Nirnaeth Arnoediad in the prologue.
-
The Fall of Gondolin and Raising of the Star. Put the War of Wrath and the fate of the Silmarils at the end of this movie.
I'm not sure where we can put the Fall of Doriath, but I'd put it in The Fall of Gondolin instead of Beren and Lúthien. I don't want to ruin the end of Beren and Lúthien by ending it with their son and grandsons killed.
