Tolkien did not appoint Any movie screenwriters to continue his legacy. He opposed all of this exploitation. He did not want the gaps in lore filled. He wanted the gaps to remain, so that they lent the works he Did publish a sense of timeless mythic depth. Boyens Jackson etc are all opportunists seeking to advance their own careers and line their own pockets. If they truly cared about Tolkien and his legacy they would respect his wishes and leave his works alone. Chris Tolkien said that Jackson Boyens etc eviscerated his and his father's works. These people Know Tolkien opposed all this and they do it anyway. They know no shame.
