Integral Cut
I'm a huge fan of this movie. Of the two commonly-available versions, I prefer the unrated of course. But I always felt it was missing something when you take out the weirdo scenes of Hill hypnotizing Meg's father and others. That material in particular makes the plot make more sense; otherwise some aspects of it (Meg's father turning angrily on Cain, and certain Hill scenes where he still attempts to hypnotize people like Meg and West) are kind of incoherent.
There's an "Integral Cut" on recent limited Blu Ray releases that incorporates this material back into the unrated version. Does anyone know if this cut has made it to DVD yet? I'm getting nowhere with online searches which tend to turn up a lot of results about the recent Blu Rays. If it's not on DVD yet, it ought to be!
