I watched this excellent horror movie last night (I've seen it before). George Zucco stars in a double role as a doctor and his own evil, deceased brother who dabbled in the occult while he was alive. And maybe still does in the beyond. Dwight Frye is also in there more or less repeating his part from DRACULA. Don't believe this deadbeats at IMDb who rated it 4.5/10!
There's probably awful PD dvds around but the Retromedia disc I bought uses a great looking print.
PS: the 4-film dvd I linked to is the same as the one I bought. Amazon has listed it as an Image Entertainment release but the copy I have clearly says Retromedia on the cover and on the disc.
