Onslow Stevens is excellent as Dr. Edlemann
The best thing in House of Dracula is not the deliciously outlandish female Ygor, the spores, the prospect of Larry Talbot actually being cured, the rather late-in-the-game wish of Dracula (after centuries) that he, too, wants to be cured, the nightmare sequence of Edlemann, but Stevens himself. He's a very fine actor and had been in movies for quite some time. His transformation from the dedicated doctor to a raving lunatic is quite believable and even scary at times. The worst thing in this Universal monster "windup" is Carradine as the Count. I swear, even Lon Chaney, Jr. in Son of Dracula had more malevolence and sinister power. Carradine was a fine actor used best by John Ford, most notably in The Grapes of Wrath and, my favorite use of him, in Drums Along the Mohawk. But here he is just BORING. The dialog between him and potential victim Martha O'Driscoll is mind-numbing: remember the Gladys Knight song "Midnight Train to Georgia", with the "my world, your world, his world...?" Well, transpose that to Carradine and O'Driscoll: "my world is calling you." "Your world seems strange to me" "My world will become more familiar to you." "Your world is coming closer to me."
Enough already with the worlds!
