I mean damn, I honestly can't even imagine how they're going to completely overlook it when he converted C.S Lewis.
When asked what the purpose of life was he said: "It may be said that the chief purpose of life, for any one of us, is to increase according to our capacity our knowledge of God by all the means we have, and to be moved by it to praise and thanks."
And in later years he opposed Vatican II, especially the liturgical reform, continuing to answer in Latin instead of English during liturgy.
That and many other things paint the character of a devout Roman Catholic which he was and he certainly saw his faith as the center of his life.
Yet we are going to have a documentary about him that's gonna be most likely so PC to such an extent they won't even mention it.
