Subject for the Second film?

[William Cloud Hicklin]

What we do know is that CT was annoyed by the Jackson movies & is unlikely to sell any further rights,

CT's no-sale position long, long predated Peter Jackson. If it wasn't lifelong, then the Rankin-Bass Hobbit was surely enough to cause it!

Remember also that even assuming Adam replaces his father on the board, he's only one director out of three; and Baillie and Michael George are two decades younger than Christopher and so likely to be around for a while yet.

One might also want to parse some othe Adam T statements. Interviewed at the CoH launch:

Asked how he feels about the publicity his grandfather's work had generated over the years, he says it makes him "sad".

"Everyone talks about the brand, the franchise and the films," he says. "People obviously forget there's a man behind it, that he wrote it for his reasons and the books are wonderful.

"I'm certainly not unhappy about the success they've had, but it's a shame that it should become a brand. It's a work of art."

And from the Estae website (which is in fact Adam):

The Estate exists to defend the integrity of J.R.R. Tolkien’s writings. Christopher Tolkien's work as his father’s literary executor has always been to publish as faithfully and honestly as possible his father's completed and uncompleted works, without adaptation or embellishment.

Are there any plans to produce a feature film from The Children of Húrin ?
There are no plans of this nature in the foreseeable future.
