I want to get a head start on our annual Oscar party. It is traditional to dress up as character from a recent, popular (or nominated) movie). And I hate doing it.
Come someone help put on a few accessories to become the most amazing movie character. Please no construction, no dyeing, no intricate makeup. I want a hat and a shirt (or something of similar effort).
By the way, I am a tall, thin male. I thought of Avatar but the blue paint was just too much for me.
Wear a suit and tie, pull a suitcase behind you – you’re the protagonist of “Up in the Air.”
It would help if you were also absurdly good looking, of course … 
Oscar costume? No problem!
Seriously, what about the Boy Scout (Russell) from Up? Easy, especially if you know a Boy Scout.
You could get some desert military duds and a fake bomb and be one of the bomb techs in The Hurt Locker.
Brown pants, brown herringbone sport coat, brown bow tie, and a bunch of balloons: Up.
Military duds, WWII-syle: Inglorious Bastards.
Tall, thin male, eh…OK, buy a frumpy dress and wear it and talk in a high pitched voice and be Julia Childs/Meryl Streep.
You can eat all the food at the party and bitch about it being too bland, not fresh enough, etc. Throw in a few French words whenever possible.
Do you have short, and/or gray hair? Get some baggy pants, a tank top, and some silly putty, and you can go as Col. Quaritch.
Bah, beaten to the Oscar the Grouch joke.
I see the Boy Scout from “Up” was suggested. The old man wouldn’t be too hard either. Or the old man (or his wife) as a little kid, wearing a leather aviator helmet.
Do you look anything like Wikus from District 9?
Short sleeve collared shirt, Brown stripped tie, Paint-Ball vest, ID on a lanyard, slacks, clipboard, and a mustache. Extra points for stenciling MNU on the vest, talking in a South African accent, and…
Wearing a lobster like monster claw on your left hand/arm
