Poverty Row Werewolf Thriller!
18 December 2004 | by (Ottawa, Ontario, Canada) – See all my reviews

"The Mad Monster" is another of the low budget little horror movies turned out by poverty row studio PRC in the early 1940s. In spite of some of the comments that I've read on this picture, I rather enjoyed it.

Basically the plot involves mad scientist Dr. Lorenzo Cameron (George Zucco) experimenting on his dim-witted assistant Petro (Glenn Strange), turning him into a werewolf. It's the old story of a scientist trying to create a super race in order to build an invincible army and you guessed it, take over the world. At the same time Cameron seeks revenge on those who had publicly humiliated him when he first presented his ideas, by turning his mad monster upon them.

Director Sam Newfield gives us an entertaining little movie. In spite of its limited budget, it provides a creepy mist filled atmosphere, as the monster stalks its victims. It also aided by the casting of Zucco and Strange as the two principal characters.

Strange plays Petro not unlike "Lenny" as played by Lon Chaney Jr. in "Of Mice and Men" (1939). He also does a creditable job as the werewolf of the piece, again not unlike Chaney in the Universal series. Zucco was PRC's resident horror actor, a sort of a poor man's Karloff, and was always excellent in these roles. Strange usually played the Chaney like parts for PRC.

The standard hero Tom Gregory (Johnny Downs) and heroine Lenora Cameron (Anna Nagle) round out the cast.

If you are a fan of the old B & W "B" horror flicks of the 40s, then I'm sure you'll like this one.
