lots of great movie titles, but so far I haven’t seen one of my favs
Sweet Sweetback’s Baad Asssss Song
Others in my collection include:
**The 5000 Fingers of Dr. T
The Kid Stays In The Picture
How To Get Ahead In Advertising
In The Realms Of The Unreal
Harold & Kumar Go To White Castle
The Lathe Of Heaven
Orgazmo**
All excellent movies, too. 
then there’s all the **Russ Meyer ** movies. To name just a few…
**Faster Pussy Cat Kill Kill!
Beyond the Valley of the Ultravixens
Motorpsycho**
Andlest we forget that bastion of B-movie goodness:
Earth Girls Are Easy
The Persecution and Assassination of Jean-Paul Marat as Performed by the Inmates of the Asylum of Charenton Under the Direction of the Marquis de Sade
Maybe not the best, but certainly the longest.
Also: A Long Day’s Journey into Night and The Iceman Cometh. Eugene O’Neill wrote some good titles (as well as some decent plays).
Kentucky Fried Movie
Stop or My Mom Will Shoot
The only title I can think of that was thrust upon the movie, because they didn’t have the money to correct the misspelled title:
Rat Phink A Boo Boo
Then there’s the classic double-bill at the XXX theatre:
THAR SHE BLOWS with HAWAIIAN THIGH
“Shallow Grave”
“After Dark, My Sweet”
“A Very Long Engagement”
“The Ladykillers”
“The Incredibles”
“Casablanca”
“Star Trek II: The Wrath of Khan”
…all very evocative to me.
These titles are all balm for my soul, wounded from such titles as Gladiator, Titanic, Hoffa, Chaplin, Selena. (Yes yes, some of these are biographies, but we can have interesting biography titles! See Man in the Moon, The Aviator, Coal Miner’s Daughter, etc.)
Exceptions: Fargo (it’s not ABOUT Fargo), Amedeus (did we know it was his middle name BEFORE this movie?), Rocky (it wasn’t an annoying trend in 1976; see me later on sequels with numbers)
Titles I love:
Dangerous Liaisons
Married to the Mob
Gods and Monsters
Smilla’s Sense of Snow (originally a book title)
A Clockwork Orange
I’d like to disagree on this. The film itself might not be one of the greatest works of art ever, and the idea of having killer tomatoes as the weapon of choice for your movie villain is somewaht strange, but the film actually is about killer tomatoes attacking, so I’d say the title is pretty descriptive, not just for laughs.
Revenge of the Surf-Boarding Killer Bikini Vampire Girls I’ve only seen one scene played out and it didn’t look very intellectually stimulating…
I almost forgot that timeless classic, “I Spit on Your Grave”.
Seen in The Simpsons on a double bill with “I Thumb Through Your Magazines”
What??? Nobody has mentioned “Cannibal Women in the Avocado Jungle of Death”. http:www.imdb.com/title/tt0094934/
Starring Shannon Tweed, Adrienne Barbeau, and Bill Maher, a strange combo if ever I saw one.
OK, how 'bout this for a (admittedly bizarre) double-feature:
The Incredible Mr. Limpet followed by The Talented Mr. Ripley. 
Fitting that **SG ** started this thread.
Every Man for Himself and God Against All.
How 'bout Oh Dad, Poor Dad, Mama’s Hung You in the Closet and I’m Feeling So Sad
The Man Who Shot Liberty Valance (both the title and the song were way better than the movie tho’)
The Ghost in the Invisible Bikini
sex, lies, and videotape
My first was just a joke, so now I will entertain you with some actual good titles, for me atleast. It’s a short list as I don’t really feel like thinking hard or searching at the moment.
Ichi the Killer
Happiness of the Katakuris
Meet the Feebles
Pulp Fiction
Dr Strangelove or: How I learned to Stop Worrying and Love the Bomb
Brazil
Naked Lunch
Love and Death
Pi
Blazing Saddles
Koyanisqatsi (Bite me, I love the overly pretenious title AND movie.)
2001: A Space Odyssey
Delicatessan
12 Monkeys
Falling Down
Raising Arizona
Harold and Maude
Hamburger Hill
Lolita
Fear and Loathing in Las Vegas (Does this even count?)
Gigantic: A Tale of Two Johns
This is Spinal Tap!
These Kids are Alright
The Filth and the Fury
Pink Flamingos
How to Draw a Bunny
The Brave Little Toaster
Tideland
Waking Life
Requiem for a Dream
The Big Leboski
Army of Darkness
Next Stop Wonderland
Buffalo '66
The Ice Storm
Trainspotting
Dancing at the Blue Iguana
I’ll have to really think about it later I suppose. That’s such an insanely small list compared to the really great titles (IMHO) that are out there.
Killer Clowns Form Outer Space. They came down in Circus Tent UFO’s. They shot people with cottoncandy cacoon guns. They drank your blood with Krazy Straws. To kill them you had to break their noses. They are evil alien clowns. I mean come on here. This has to be the best movie EVAR!
