The published Silmarillion ends with the recounting of the voyage of Eärendil the Mariner, but this is due to an editorial decision by Christopher Tolkien. The Silmarillion as Tolkien originally wrote it ends with a prophecy by Mandos about the Dagor Dagorath, often referred to as "The End".

Is Silmarillion finished?

Tolkien never completed The Book of Lost Tales; he left it to compose the poems "The Lay of Leithian" and "The Lay of the Children of Húrin". ... The Quenta Noldorinwa was the last version of The Silmarillion that Tolkien completed.

Will The Silmarillion be made into a movie?

And it is true, Peter Jackson will never obtain the rights to make a film adaptation of The Silmarillion, but nor will any other film-producer. Unlike The Lord of the Rings and The Hobbit, the film rights for The Silmarillion were never sold and still remain with the Tolkien family.
