A must-see for Tolkien fans, or for Lewis fans. From a special on Tolkien's work, a recreation/portrayal of a discussion between the two close friends.

It shows the closeness between the two that they could have such opposing views, on such a controversial topic, and keep it civil and congenial.

If only such closeness weren't needed. I love discussing religion, both the sharing of my own beliefs and hearing those of other people, but it is such a delicate topic...
