Wolf Blood (1925)
Directed by George Chesebro and Bruce M. Mitchell
Featuring George Chesebro, Roy Watson, Milburn Morante
What it is: Lumberjack lycanthropy
When the head of a logging camp is injured in a fight with rival loggers, an emergency transfusion is given to him of blood from a wolf. The rumor begins to go around that he is now a loup-garou.
The movie is nearly half-way through before we even get to the fight that mentioned in the above plot description; most of the movie to that point has been a romance/melodrama involving rival logging camps and a love triangle between the foreman, the doctor and the female owner of the logging camp. Pretty much nothing in the movie earlier than that hints at any turn into horror. Still, once it does take the final turn into horror territory, it has its moments; there are some scenes of the foreman being tortured by the thoughts of what he might have done, and there is a nice sequence of him following a ghost pack of wolves into the forest. Incidentally, the ghost pack is all in the foreman's mind, and that's not the only product of an over-active imagination at work here, either, and if you've seen enough horror movies that emphasize people fretting over what they don't remember doing but thing they might have done, you won't be surprised at the final revelations. Overall, it's not bad, but not quite satisfying for the full-blooded horror fan.
