The annual DVD rip of the 24 "prequel" bridge between seasons is floating around the net. Most of the links I found to it were dead, but this one was still live as of last night:
24 Season 6 Prequel
Agree with most of the Internet chatter that the RAV4 product placement here is pretty lame. Otherwise it's entertaining to get a little sneak peek that's part of the official canon yet not as spoiler-filled as the trailers/commercials that I can't stand to watch, even if it has no "real" bearing on the story other than a couple of minor hints of background and timing.
