[Boromir88]

We all know about the part of the will that named CT as JRR's literary executor. Here are some other moments when JRR talks about the importance of Christopher in the writing process and which is probably why Christopher has so many strong feelings about the books and upset over film adaptations:

A map of the Gondor area is perhaps the most urgent. I am hoping to get my son Christopher to produce one from my drafts, as soon as possible.~Letter 150

'This book {LOTR} has become to be more and more addressed to you, so that your opinion matters more than any one else's.'~Letter 78 (Dated Aug. 12, 1944 to Christopher).

"But I made a very great effort to finish the Hobbit sequel, and chapters went out to Africa and back to my chief critic and collaborator, Christopher, who is doing the maps"~Letter 105

JRR clearly felt that Christopher was an important person when it came to creating his story. And I think CT has taken on that duty quite admirably because as the will states...Upon trust to allow my son Christopher...he was trusted by his father to act as his Literary Executor over all unpublished works. I believe this is why CT has such strong beliefs about movie adaptations, just as his father did, because he was placed in such a position to do so.

I don't know Simon, it seems like he had great times with his grandfather, but if you ask me he seems like there was a strain between him and Christopher even before the movies came out:

Life wasn't great after his death....
My father moved to the South of France with his second family and I hated having to be away at school. I missed my grandfather very much. My father has always been in charge of my grandfather's literary estate, and about four years ago he started to think about who would succeed him on the board of the company which administers the Tolkien estate. He named new directors to join him and I was not one of them.

Here is the full account Simon tells...I greatly enjoyed reading the memories Simon had with his grandfather.
