This film has a special interest to me because it was the only one with my grandmother, Mary Frey, on screen. It has all of the usual old spooky house elements with lots of screams and surprises. Along with this there are the stock incompetent police, and elements of classic farce. But I think the director had some fun with these elements. Check out the scenes with the grinning skeleton. With all of the special effects now available we can't take this film seriously, but we can laugh at the clichés. One notable flaw is the music which does not go well with some of the scenes. It is way too upbeat when it should be communicating mystery. However, it is very soft so it is not obtrusive.
The séance scene has a little history. According to my father it was filmed during an aftershock of the Long Beach earthquake. But the actors were stage professionals and kept going despite the heavy lights swaying over their heads. The director was so impressed by the intent expressions that he said it was perfect with no retakes needed.
OK, the characters are one dimensional, but that is common in this genre. Lugosi has ample opportunity to use dramatic facial expressions and outbursts. Very small children may find this movie frightening. The only available copy from Sinister Cinema is a fairly good, but soft focus print.
