Clash of the Gods: The Lord of the Rings

HISTORY This show uses interviews and dramatic re-creations to suggest what might have influenced English author, poet, philologist and professor J.R.R. Tolkien (1892-1973) in the writing of his trilogy The Lord of the Rings, in which individuals’ quests to do their duty, no matter what the odds or cost, save Middle Earth from terrible evil. Catholic viewers will recall that Tolkien said his Catholic faith underlay his work. Advisory: Beware of scary images.
