Indestructible Man (1956)

Starring Lon Chaney Jr., Casey Adams, Marian Carr, Ross Elliott, Stuart Randall
Directed by Jack Pollexfen
(actor & director credits courtesy IMDB.com)

A condemned convict dies in the gas chamber, but after being restored to life by a scientist, and given great strength and invulnerability, sets out for revenge against the men who betrayed him.

This is far from a good film, but fans of Chaney's monster movies of the 1940s may find some enjoyment in it, as I did, seeing the favored actor again playing a monstrous character, and given more screen time than in most of his other 1950s roles.  Chaney becomes mute after scientist Robert Shayne "burns out his vocal chords" in resuscitating him with electricity, but given Chaney's other mute roles during the decade, it's likely his alcoholism played some part in that plot detail.  However, an early jailhouse scene comes off well for the actor, and a shot of simmering hatred in his eyes is well utilized.  The film is narrated by actor Casey Adams, also known as Max Showalter, playing a police detective who gets chummy with Chaney's girl, and has a surprise for her at film's end that wouldn't play well in any era but the 1950s.  Jack Pollexfen directs, and I've been fond of other pictures he's written and produced, but his direction is a bit too pedestrian here, not taking advantage of opportunities to heighten Chaney's menace and build suspense.

The Monster That Challenged The World (1957)

Starring Tim Holt, Audrey Dalton, Hans Conried, Barbara Darrow, Casey Adams
Directed by Arnold Laven
(actor & director credits courtesy IMDB.com)

A Navy commander spearheads an investigation into the mysterious deaths of divers in California's Salton Sea, and discovers giant radioactive mollusk monsters are to blame.

Not a great movie, but a lot of fun, with horrific and convincing looking monsters, although they don't really resemble mollusks that closely, as a video presentation during the movie makes painfully clear.  Presumably giant puppets patterned after the ants in the 1954 classic Them!, the creatures unfortunately don't have much mobility which limits their effectiveness on screen, but they're so scary looking, and with Heinz Roemheld's foreboding music accompanying their attacks, they definitely make a creepy impact.  Star Tim Holt was on the downhill side of his career, and looks like he's carrying a bit of weight, but he's a fine enough choice for the picture, and although his scenes with Dalton as a widowed secretary pining for him are a bit clumsy, they came off for me all right.
