I *really* hope the documentary explores Tolkien's ardent Christian faith as a devout Catholic--which heavily influenced all of his major works. As opposed to turning it into a dryasdust recital of Tolkien's personal chronology. Or worse, a militant secularist scrubbing to sanitize or even reinterpret the historical record.

If it does include a more-or-less accurate and respectful coverage of Tolkien's Christian world view (as I thought the Shadowlands movie did about CS Lewis, despite some artistic license with the facts), I'd look forward to seeing it. When I see a documentary on any important historical figure--Christian, atheist, agnostic, or adherent of some world religion--I want to know what they really thought, what influenced their thought and work most, regardless what I may think of them.
