Mutiny In Outer Space (1965)

Starring William Leslie, Dolores Faith, Pamela Curran, Richard Garland, Harold Lloyd Jr.
Directed by Hugo Grimaldi
(actor & director credits courtesy IMDB.com)

A fungus from the moon is accidentally brought aboard a space station, and as it spreads, the station's commander refuses to let the crew take the threat seriously.

An interesting, but very low budget film which recycles models and other equipment from Grimaldi's previous productions, it's well-assembled but lacks excitement and enough suspenseful scenes with the growing fungus.  Garland's character's mental illness in the script gives the plot a unique angle, but it's not sufficiently explained whether he's having hallucinations or just doesn't want to risk losing his command.  Nevertheless, I enjoyed the cast, and especially the music, which included some selections from The Phantom Planet and others that sounded like cues from the Universal horror library.  Overall the film is okay, but may be most notable for being a possible influence on the more action-packed The Green Slime some years later.

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.
