Secrets of Middle-Earth: Inside Tolkien's The Two Towers.

This well-received British series, hosted by Grant McTavish, digs deep into the second volume of J.R.R. Tolkien's epic and, with the help of computer technology and the artistry of the Brothers Hildebrandt, looks at Middle's Earth's locales, language, cultures, residents and more. Tolkien expert Michael Stanton and historian David Doughan lend extra credibility to the analysis.
