The 1959 blank-and-white British horror-whodunit film "Jack the Ripper" was released on a special edition Blu-ray last year (product page). But it was sold out before much of the public had even heard of it (maybe that was why there had been no threads here). It was made in a limited quantity of 1500 copies, put on sale on last year's Black Friday, sold out that very day, put on sale again last week for some leftover copies, and again sold out that day.
The Blu-ray comes with 3 versions of the film: the British, the US, and the continental European versions. Sadly, only the US version has watchable picture quality (similar in quality to the Amazon Prime streaming version). The US version also has one shot in color, which is thankfully retained here. The continental version looks the worst (like a duped VHS copy), and sadly, it is this version that has all the frontal nudity.
The film is pretty good for a B-grade, Hammer-esque thriller yarn. The motive for the murders, as shown in the film, is completely laughable, as expected in this kind of affairs. But I was happy to see a RARE defense of doctors in films like these that almost always scapegoat the doctors. The defense was made by a doctor who, upon hearing accusations against doctors by a detective, immediately opened up his surgery bag, showed the knifes inside, and said sarcastically, "Well, here are my knives! Arrest me, why don't you!"
