This entry will cover a plethora of things, such as favorite vamps, actors who should play vamps, best Halloween costumes for 2012, horror films to watch on the 31st, etc. There may be a part two, but for now...
HORROR FILMS FOR HALLOWEEN
This is the lsit of films I'd recommend if you want a good scare, or a good laugh. Let's face it--some horror films are just plain goofy. But for the most part, this list is full of classics.
Carrie, Halloween, From Dusk Till Dawn, Freddy vs. Jason, Nightmare on Elm Street, Dawn of the Dead, The Exorcist, Jaws, Insidious (it will fuck you up), Night of the Living Dead, The Shining ("I'm not gonna hurt cha--I'm just gonna bash your brains in." Oh, Jackie boy...), The Bad Seed (creepiest little girl in a film, for sure), The People Under the Stairs (messed up my childhood; a tad ridiculous to watch as an adult), Fear (Mark Wahlberg does psycho well!).
Okay, so the two obvious ones are the Gangnam Style guy and Big Bird. My personal dream costumes are Michael Jackson's Smooth Criminal, and Lucy Ricardo (though not a polka dot dress. Honestly, I'm not even sure how that became one of her staples). But here are some you may want to consider if you're in a pinch and on a budget:
Buy a pair of decent fangs for twenty bucks or less, and put on some stuff at home, like combat boots, something involving leather, chains, and or black, a corset, a really cool coat, outrageous eye makeup, black nail polish, and maybe some fake blood for your mouth.
Pretty much, all you need is a light blue button down, a pair of khaki pants and a red baseball cap. 90s classic, uber geeky, and yet, wicked cool.
A red and white striped shirt and a pair of skinny jeans, and a snowball red and white hat with some hiking boots. Oh, and a sack of crap and a walking cane. Cheapish costume.
Get some wrap gauze or white streamers and go to town.
Memorable Costumes I've seen over the years:
Wilson the neighbor from Home Improvement, Professor Henry Jones, an 8 foot tall Predator, Carmen Sandiego (when are they making a film for that?), and a little kid dressed as Flavor Flav.
