40 Days of Night(mares) Day 18: Favorite Horror movie Filmed in Black and White

I almost had to toss a coin on this one. I had two highly influential black and white films in mind. Both are considered the master templates of their particular horror sub-genres. But one of them tangentially caused the birth of the Twilight franchise, and that's unforgivable, so Nosferatu, buddy, sorry, you're outta here.

Original Emo Hipster: He sucked blood before being shiny was cool.

All kidding aside, Nosferatu is a wonderful early example of horror and ranks up there with the Hammer version of Dracula in terms of generational influence. If you haven't seen it, you are missing out on a huge piece of the genre's history.
And speaking of influence, there are zombie films that predate Night of the Living Dead, but few have the kind of lasting impression George Romero's little independent film has. It would go on to inspire direct sequels, remakes, homages, spoofs, and the very idea of the lumbering undead for decades to come and into the future. And, because it's copyright expired, it's now public domain, so it continues to get played every year.
It's reached the pantheon of classic film. To today's gore-hungry, quick-cut, one death every 8 minutes audiences, it may seem a little plodding and slow paced, but that's where the true masters understand horror. It's not the actual violence and death that's scary, it's the buildup. That's something that goes missing all too often.
Romero's film is long considered an allegory for race relations, largely due to the casting of a black man as the lead protagonist, who (I don't know if there is a time limit on spoilers, but here's your warning anyway... SPOILER AHEAD!!!) is shot dead after being the only person to survive the undead onslaught and just as help arrives (white help who shoot him on sight).
I love zombie movies, and this is the one that started it for me.
I give it a full 10 out of 10.
