The Beast With Five Fingers (1946)

Starring Robert Alda, Andrea King, Peter Lorre, Victor Francen, J. Carrol Naish
Directed by Robert Florey
(actor & director credits courtesy IMDB.com)

After a great pianist dies in an accident, his hand disappears from his coffin, and its trail leads to a murdered man, causing a small Italian village to suspect it's returned to life for revenge.

This dark tale was scripted by Universal horror veteran Curt Siodmak and directed by Robert Florey, who helmed Bela Lugosi's Murders In The Rue Morgue, the two bringing an impressive horror pedigree to the picture.  The special effects rendering the hand as it moves on its own are excellent, and there's fine performances from the entire cast.  Peter Lorre is especially captured well by the cinematography of Wesley Anderson, with many eerie closeups of his eyes and face as the actor speaks to us through his expressions as well as his voice.  An integral part of the film is the musical piece Francen's pianist and later his hand on its own performs, Chaconne in D minor BMW 1004 (per IMDB), which composer Max Steiner builds an excellent musical score around, incorporating its themes for dramatic effect throughout the story.  Overall it's an excellent and entertaining film in my view, and despite the period and provincial setting, it holds up well as a horror film today.

House Of The Black Death (1964)

Starring Lon Chaney, Jr., John Carradine, Andrea King, Tom Drake, Dolores Faith
Directed by Harold Daniels
(actor & director credits courtesy IMDB.com)

The head of a coven of Satan worshippers seeks to wrest control of his family's wealth from his brother, who is determined to oppose him.

This one's pretty much a stinker, which is a shame, because actors Lon Chaney, Jr. and John Carradine, who had headlined many a quality horror film between them, deserve a much finer showcase of their talents.  To cast them as warring brothers with supernatural powers, a tremendous hook for their fans, and then afford them virtually no scenes together, is almost incomprehensible.  That is far from the film's only flaw, which also suffers from a vague plot and haphazard editing, including a pointless routine by a nubile dancer which is cut into the film three different times, cutting away from the action and making little sense.  Another scene of a man's transformation into a werewolf is poorly cut as well.
