I think we have a winner
 

"The scene" in Cache. I'll bet anybody who sees this movie will agree with me.

The Life of Bryan

Where he gets picked up and dropped off again by aliens after falling from the tower. Certainly beats landing on an awning or in a fruit vendor's bin, I guess.

Tampopo - The begining scene. Not so bizarre but yet bizzare enough.

Man shushes the theatre patrons (in the movie) and talks to the movie viewers (outside the screen) and explains we are watching his story, before he dies.

A great film about ramen. A story about ramen? That's bizarre but now I'm hungry.

Just off hand, one of the bizzarrest scenes is from "Bad Lieutenant" with Harvey Keitel.

"Oooooo----oooooohhhhhhhhhhhhh!!!!!!".

Slim and the Bomb
 

Slim Pickins, doing the emergency list check off in the B-52 in "Dr. Strangelove" "...one .45 automatic, condom, $50 in rubles...man I could have me a ball in Vegas..."

And...riding the bomb down at the conclusion of the flick.

One of Kubrick's first movies.

Not to be picky, but STRANGELOVE was well into Kubrick's career--around his seventh film, between LOLITA and 2001.

Kubrick
 

Good Call. Shudda said earlier instead of first.

Lolita was 1961
Strangelove was 1964

There are a number of internet film lists; looks like he made a total of 16 - including 3 shorts. The 1st short was made in 1950, called "Day of the Fight," The last was "Eyes Wide Shut according to Netflix list, and Amazon. Wasn't he working on a thing call "AI" when he died?

Still, I love 'ole Slim..

That was my recollection - I think the bulk of it was completed by Spielberg...other than some very nice cinematography and a 'robotically poetic' performance by Jude Law, I thought AI was only slightly better than Bicentennial Man which I thought was incredibly drawn out and hence grew dismally boring. I think Spielberg is an intensly creative filmmaker and a master imagry craftsman (after his fashion) but I think AI would have been a far superior film experience if it had been a purely Kubrick product.
Just my dime - (2 cents plus inflation)

The opening scene in Titus where the kid with the bag over his head playing frantic table top war games had me going "...the hell?"

I love that scene (and the whole movie), but wouldn't put it on the "most bizzare" list... it's frighteningly real! ;-) Check out the recently released restoration on DVD, the documentary is excellent. I think this is a little closer to what Major Kong really says:

Trivia: originally the line said "a fella could have a pretty good weekend in Dallas," which is what Slim recorded. But before the film was released JFK was shot and they decided the Dallas reference wasn't cool. Listen carefully and you'll hear where they overdubbed it with "Vegas".

Also, that part was originally to be played by Peter Sellers, but he was injured on the set and couldn't climb into the cramped cockpit so they brought Slim in at the last minute. The same accident led to Dr. Strangelove's wheelchair - talk about serendipity! And the glove which Stangelove wore was actually one which Kubrick kept around so he could focus lights himself - Sellers grabbed it and started clowning around. Like I said, the documentary on the DVD is full of good stuff :-)

Hey Boyd, loved the check list!

(You can't fight in the war room!)

What you saw Slim do in the movies didn't even come close to his antics and escapades in real life. I met him several times, as he was a good friend of my uncle, who was a horse trainer and stuntman. Slim worked the rodeo circuit before the movies and was one of the more popular rodeo clowns. At a big Pow-wow of the Klamath tribe in the 1950s, I saw him capture and enthrall the whole gathering, with his wild dance, wearing buffalo robes and a full head with horns. He spent a lot of time in Oregon throughout his life and was
endeared to us all.

Kubrick didn't tell Slim that it was a black comedy and had him play the role straight as if it was an action war movie. How he got slim to ride the bomb that way most have been genius.

Got to love James Earl Jones in the cockpit, too.

check out "The Killing" and "Paths of Glory."

Without thinking about it....here they are.
 

TAXI DRIVER, when he takes his date to the porn movie.
AUDITION, the sawing of the foot.
PULP FICTION, Bring out the Gimp.
DELIVERANCE (pulps older brother as far as this scene), Squeel like a pig!
HENRY: Portrait of a Serial Killer, that rape scene is way too much.
FREAKS, Gooble Goble, gooble goble one of us.
CLOCKWORK ORANGE
THE EXORCIST, when she stabs herself with the crucifix.
TEXAS CHAINSAW MASSACRE(original), that whole movie is too much...but not more than my next pick...
IN THE CUT, the whole thing was one bizzare bad scene.

Yup, that pretty much covers it, but some scenes which do it for me are found in, "Fire, Walk With Me." :)
