The Black Room (1935)
Surely a sparkling gem for Karloff fans. Playing double roles for the twin brothers demonstrates what a great range of performer he was. Karloff plays both the devilish and kind brothers, but in addition, he portrays the nasty brother imitating the gentle one. And that's what makes this masterpiece fun along with great sets, costumes, and lighting. It was like a Gothic fairy tale with good amount of horror elements.
Director Roy William Neil did an excellent job; especially having the two twins in the same room together really boost this underrated film. Kudos to Columbia Pictures, they showed that there was more to Karloff than just the Frankenstein's monster.

The Man They Could Not Hang (1939)
This is my first Karloff's "Mad Doctor" film and it just straight blew me away! Karloff was magnificent as
Dr. Henryk Savaard; along with the beautiful storyline & fantastic dialogs his character's transformation from kindly dedicated scientist to a madman bent on murder & revenge was simply brilliant to watch.
