Most director commentaries are disappointing. Many makers you'd expect to be interesting, aren't. They rarely discuss conceptual issues of any sort. Good commentary tracks are often found on otherwise mundane films, e.g. the director's commentary on Stir of Echoes is very revealing about filmmaking. Other worthwhile commentaries I've heard include Three Kings, and Even Dwarves Started Small (Herzog is great, but there are two other folks on the track who have little to say). The commentary on Texas Chainsaw Massacre is revealing of the mindset behind the film (basically Beavis and Butthead style adolescent-sadist humor), and in some ways scarier than the movie. But I think my favorite is Starship Troopers, which is very funny among other things, as Paul Verhooven is at pains to correct the impressions left by many reviewers who somehow failed to see the satire in the film, and Verhooven's basically progressive interpretation of the film as critique is regularly subverted by screenwriter Ed Neumeyer, who seems to have darker pleasures lurking in his interpretation. ---- Online resources for film/TV studies may be found at ScreenSite http://www.ScreenSite.org
