Some of these lobby cards are gross man. There are some bios and filmographies for the cast and crew, a DVD credits index and a Grindhouse Releasing ad on the disc, so you can find out more information about these guys. You'll find that in his biography section. It's really a nice little package, when you get right down to it. I wish more films got this treatment, extras-wise.
Every plot point is listed in full text.
You could literally read the entire film by scanning the 50 chapter stops on the insert. This film is certainly not for everyone and the people it is for aren't universally going to be happy. But the extras make up for certain video problems, so if you're a fan, I wouldn't stay away. If you're just among the curious, rent it before you buy. And if you're a huge fan and don't own the film in any format you might want to consider getting the DVD and the original laserdisc.
