In a scoop from, PoltergeistIII.com, someone affiliated New Wave Entertainment recently scooped the site with some info on the anticipated DVD release of a special edition of Poltergeist.

I don't know anything else on the DVD save for what you know. They are having interviews with JoBeth Williams, Craig T. Nelson (I believe that's what I heard) and the hold out was Zelda Rubinstein due to prior commitments.

Short of that we were very honored to be asked to have this film crew with us as we investigated the nicely haunted Pierpont Inn in Ventura and a couple of other places. We held our conference in May but were asked not to release any information until June/July while they completed the segments for inclusion on the DVD.
