I will rip off the Werewolf badly George I will I will..
19 October 2004 | by (United States) – See all my reviews what a dull movie. Here you have 'Sam the Barkeep' from Gunsmoke shambling around in a blatant Lon Cheney knock-off, wearing the world's worst lupine doo while stumbling after George Zucco's ex-colleagues. Zucco himself does his Moriarty routine as always, and is easily the best thing here, while Anne Nagel once again stars in a Monogram poverty-row B flick.

It's a slow, slow movie, where the hillbillies act rather badly, the victims scream in a monotone, and the dry ice is used and abused frequently. I enjoyed the vines in the 'swamp woods'--clearly they doubled as clotheslines.

I have a weakness for old B genre flicks from this era, but this one-is snooze central.

Def. one to avoid unless you are a Zucco fanatic.

** outta ****. Zzzzzzz.
