As the epitome of class and style for the horror genre, Boris Karloff always came across in his films with talent, poise, and charm. This collection features a quartet of Karloff's most chilling efforts from his peak years in the 1930s and 1940s, all demonstrating his amazing range as an actor.

In The Black Room (1935), Boris plays twin brothers-one good, one evil, naturally-in a small country where beautiful women seem to turn up missing.

The Man They Could Not Hang (1939) and Before I Hang (1940) present him in his classic 'Mad Doctor' persona as forward-thinking scientists who run afoul of the law and become crazed killers.

In The Boogie Man Will Get You (1942), he sends up that image in a delightful farce.
