On the DVD: This two-disc set duplicates the original single-disc release of the film which included a handful of cast and crew interviews, and adds an additional disc with more interviews, two brief behind-the-scenes featurettes about the production design and the post-production digital colouring of the film, a couple of storyboard-to-scene comparisons and a music video of "Man of Constant Sorrow". There's also a 16-minute documentary to promote the companion Down from the Mountain concert. Frankly there's not a lot here to justify spreading it across two discs: a more pleasing not to say generous offering would have been to cram all these extras onto Disc 1 and give us Down from the Mountain as the second disc. --Mark Walker
