I might have tweeted this a while back, but it definitely deserves a mention here. Icons of Fright has a handful of unofficial DVD commentaries (mp3 format) available for download. I'm a huge Fright Night fan and commentary junkie so you can imagine my delight when I saw two tracks with cast and crew (William Ragsdale, Chris Sarandon, writer/director Tom Holland, etc). This is a trend that I'd love to see catch on. DVD extras aren't incredibly popular with the general public, but they can be invaluable tools for aspiring filmmakers.
