Not so very long ago, Mike Nelson (of MST3K fame, if you didn't know) launched RiffTrax, a website which sold audio commentary tracks which you could download and play along with your DVDs. It wasn't MST3K, but it was an interesting effort. And now, Nelson and his MST3K cohorts Bill Corbett and Kevin Murphy are stepping yet closer to their old line of works with the launch of Film Crew, a three man team which is dedicated to providing commentary tracks for DVDs everywhere (starting with inexpensive B movies, of course). Once they get going, you'll be able to purchase DVDs and listen to them with the Film Crew commentary with voices sure to put you in mind of MST3K. I can't imagine these being anything short of brilliant, myself. Swing on by and help them decide which movies to Riff on first.
