the mad monster start in dr. lorenzo cameron ( george zucco ) laboratory a he perfect his discovery of how to turn a human be into a vicious wolf like monster by inject animal blood into a human subject who happen to be his dim witted servant petro ( glenn strange ) and apparently he plan to put the serum at the disposal of the war department who will use it to create an unstoppable army of these monster and the ultimate soldier . however and first thing first a dr. cameron have his sight set on some sweet revenge on the people who dismiss his experiment and force him to resign and subject him to public ridicule . dr. cameron put his plan into action and use his monstrous creation to murder professor blaine ( robert strange ) and in an unfortunate turn of event dr. cameron be unable to control the beast and be spot by a local farmer jed harper ( eddie holden ) who spread the news like wildfire and in another unfortunate coincidence a reporter name tom gregory ( johnny down ) get wind of the story and start to investigate and he start to suspect dr. cameron and since gregory be go out with his daughter lenora ( ann nagel ) he have plenty of opportunity to sniff around . direct by sam newfield this be really low budget stuff from the 40 and even bad it dull unoriginal low budget stuff . the script by fred myton drag the extremely thin premise out to almost 77 minute which be far too long and there be no variety in the story and it basically the same thing over and over . the character be dull clichés and the mad scientist who conduct pointless experiment that create a monster and the fragile pretty daughter and the reporter who play the hero and by pure coincidence happen to both be investigate the mysterious death say mad scientist be responsible for and be romantically involve with his daughter and the dumb servant and stupid idiotic police and stereotypical shotgun wield farmer who be always accuse of be drunk . this be probably clichéd even back in 1942. the film plod along at a fairly slow pace and director newfield never manage to maintain or generate much in the way of excitement or atmosphere which be a bad thing . technically the film isn not great and obviously the budget be minuscule and the mad monster itself look lame resemble an old homeless wino who hasn not shave for a few week and have have a pair of plastic joke shop fang place in his mouth . the black and white cinematography be basic and static like most film from this period while the good dr. cameron laboratory consist of a couch and a table with a few sorry piece of scientific equipment on top . the acting be stiff and wooden with petro look like he on dope throughout the entire film and zucco a the mad scientist doesn not convince and be forgettable . the mad monster be a pretty lame horror film and there be very little here to entertain although at least i make it through to the end in a single sitting which when i think about it be a bit of an achievement in itself .
