Revenge Of The Zombies (1943)

Starring John Carradine, Gale Storm, Robert Lowery, Bob Steele, Mantan Moreland
Directed by Steve Sekely
(actor & director credits courtesy IMDB.com)

After his sister's unexpected death, her brother takes a detective to her husband's home in the swamps, where bodies seem to disappear and zombies are walking the grounds.

Despite the title and the presence of Moreland, this is not a sequel to 1941's King Of The Zombies, which was also produced by studio Monogram Pictures, but has a similar plot, and Moreland again provides the comic relief, although he's not quite as amusing as he was in the previous film.  Although Moreland is probably not regarded favorably by many due to playing stereotypes throughout his career, he certainly had a talent for delivering rapid-fire one-liners, and has plenty of them here.  As a zombie picture, the film doesn't quite deliver the goods, with the walking dead having an exaggerated robot-like gait, but it's fun in its own way with a silly call for the zombies uttered by several characters, and Carradine appropriately grim and obsessed as the film's mad scientist.

The Day Of The Triffids (1962)

Starring Howard Keel, Nicole Maurey, Janette Scott, Kieron Moore, Mervyn Johns

Directed by Steve Sekely
(actor & director credits courtesy IMDB.com)

A meteor shower brings blindness that afflicts nearly all of the Earth's population, and also spores that grow into immense mobile plants that stalk human victims.

Howard Keel stars in this version of the science fiction novel by John Wyndham, which per my recollections of the book and its synopsis on Wikipedia, is not a very faithful adaptation, eliminating characters and condensing a bit too much, but still offers some effective scenes, with the triffid plants rendered about as well as one could expect for special effects of this era.  The filmmakers and actors do a good job of creating characters we can care about, and the eerie sound effects accompanying the triffids' movements are first rate.  However, the film would have been better had the screenwriters kept more of Wyndham's novel in their script.
