These early-look behind-the-scenes videos usually aren’t anything special, but Entertainment Tonight’s set visit to The Hughes Brothers’ The Book Of Eli actually yielded some information about this mostly-unknown project. Sure, we all have read the logline — a man journeys across a post-apocalyptic America guarding a book that contains the secret to saving humanity — but what’s up with this post-apocalyptic America?

Well, now we have our answer, courtesy of Mila Kunis. The actress tells us that in the futuristic world of the movie, the sun has exploded, bringing about the desolate wasteland we see in this video. Fancy that. Denzel Washington stars, alongside Gary Oldman, Ray Stevenson, Jennifer Beals, and Michael Gambon. The Book of Eli is slated for a January 10, 2010 release.
