the ghost walks (1934)

"Well the ghost walks tonight or never."
Stranded when their car crashes, a theatrical producer Herman Wood (Richard Carle), his secretary Homer Erskine (Johnny Arthur), and playwright Prescott Ames (John Miljan), seek shelter from a storm in the home of Dr. Kent (Henry Kolker), a friend of Ames. Also there is Beatrice (Eve Southern), a patient of Dr's, traumatised by the murder of her husband. Over dinner, the group throw accusations about, as to who committed the murder, a prelude to an eventful night.
Witty horror comedy, that plays with the already established format.

the vampire bat (1933)

AKA Blood Sucker. Forced to Sin.
"Vampires are at large I tell you!"
There's a serial killer terrifying the villagers of Kleinshloss, with all the victims drained of blood. The burgomeister (Lionel Belmore) and Dr (Lionel Atwill) are convinced there is a vampire in their midst, but the chief of police (Melvyn Douglas) is skeptical as is his girlfriend (Fay Wray). Suspicion soon falls onto slow witted Herman Gleib (Dwight Frye), who is targeted by vigilantes. Meanwhile the attacks continue...
As much a whodunit, as a horror. This is an effective and entertaining film, whatever it is.
