In addition to all the stuff I listed earlier, I've got some stuff in my rental queue that I'll be watching in good time:
The Invisible Man Returns (introducing the then-unknown Vincent Price)
Revenge of the Creature (I wish the 3-D version was available)
The Creature Walks Among Us
Son of Dracula
House of Dracula
Murders in the Rue Morgue
The Black Cat
The Raven
White Zombie
The Corpse Vanishes
Scared to Death
Abbot & Costello Meet Frankenstein (especially for Lugosi's triumphant return to the role he originated ... see a pattern?)
The Golem (silent - The Simpons spoofed this one last year)
The Cabinet of Dr. Caligari (silent)
The Man Who Laughs (silent - featuring the character upon whom The Joker was modeled)
