This is exciting news! I've been hoping for further progress on this release, and the fact that the company sprang for such a full length interview with Barbara definitely adds very solid gilding to this particular lily.
I think that Italian expression corresponds more to the English phrase "beyond the grave" in the sense of an Afterlife--natural or unnatural as the case may be! There are similar expressions in French and German if I recall correctly.
I wonder whether there's any hope for some of Barbara Steele's other classic Italian horror movies to be restored. Most of them circulate in butchered, mutilated versions with grainy prints, incoherent continuity, etc. There's one really good one, An Angel for Satan, that has NEVER had a proper US release--in any format!
