Well, there has been a relative tsunami of Hammer Blu-ray releases & announcements over the past couple of years (about time!). The Columbia titles (REVENGE OF FRANKENSTEIN, THE GORGON, BLOOD FROM THE MUMMY'S TOMB), remain m.i.a., but even HOUND OF THE BASKERVILLES (1959) appears to be coming in a few months. But, as with the Quatermass series (where the first and third entries are now available on Blu-ray, but QUATERMASS 2 is not), we are missing the second of the Hammer Karnstein vampire series. Part one, THE VAMPIRE LOVERS, and the third, TWINS OF EVIL, are available, but not LUST FOR A VAMPIRE.
Sure wish we could fill in these gaps!
