Nine Queens is a IQ test. Period.

If you don't get it, you are simply an idiot.
Is the awful truth.
There aren't any holes or flaws.
I read all the critics of people who didn't get it, everything is so clear...

I watched this movie like twenty times or more, first of all because I love it. Secondly because I was amazed of this near flawless script, I wanted to find a hole in the script, but everything fits and the movie is full of winks deliberately.

Gas station: either way, Juan had been following Marcos and saw an opportunity to make his entrance or He knew Marco's schedule or behaviour... or maybe he knew that Marcos was about to make the same ruse to the girl...

Gas station 2: Juan Knew about this alter-ego of Marcos, he knew that Marcos needed a partner.

Gas station 3: Consider that this complex conning had been planned carefully, everything. Any small difference or deviation from the original plan could be solved by the high quick-mind creativity of Juan. Maybe Juan had an alternate plan, maybe not. who cares, it worked. The greatest and most important antibiotic, the Penicillin was discovered by chance, who cares how Fleming discovered it, it works.
The main problem and the most risky part was the beginning, to see if Marcos would bite the bait.

C'mon Do I have to explain everything?

I think this forum shows the reason of why people doesn't like this movie, because they DON'T GET IT. Don't undestand a thing, nothing, zip.

I have very good English subtitles, I checked it myself and the translations are quite accurate.
The part of the bathroom where Marcos asks Juan, "Would you *beep* a man for fifty grands?"
When marcos says: "Putos no faltan, lo que faltan son financistas", la traduccion que tengo es: "We are not lacking pillow biters, just financiers", es simplemente excelente, jajaja, aplaudo a los que tradujeron esto.

Well, as I was saying maybe you have a lousy translation.
If you need a subtitle, I can post it here, so you can use it.

What I love from this is the fine detail of everything. Since everything, from the Spaniard to Valeria all the people involved are a part of the ruse to con Marcos, you can see surprised expression of Marcos, nothing comes as it should be for him, nothing is under his control.
First with Vidal Gandolfo who says: "If you had something to sell me you'd knock on my door just like a book peddler. But if you were a smart Argentinian, you'd try to interest me. You could, for example, have a telephone conversation with an alleged buyer and make sure I'd listen to it. But you have to be subte, You shouldn't say anything like "What? For the Nine Queens? You are crazy!" And then the cop, "Please, don't hit me. I've something to sell. But it's legal. i promise. Do you understand? It was so ridiculous!."

And Marcos watch at the Spaniard, we know he is nervous he has been discovered. But he is very smart and says "I don't know what are you talking about". You gotta have guts.

And then, the scene where Marcos is about to tell Valeria about Gandolfo's dirty proposal:
Valeria: Chito, go get Federico. Tell him to come.
Marcos: No need to bring in the kid.
Valeria: Why not? We share expenses, we are roommates. He's got a right to know.
Marcos: To know what?
Valeria: Whatever it is you are going to propose. I know you. ("I know that tone in your voice", this is not translated in the subtitle). What do I have that interests you?

Here he is discovered again, and we can see the distress in the face of Marcos, he is being discovered everytime, this is not usual, people seems to be one step further all the time and he is distressed, nervous.
I love that detail in their acting performance.

Anyway, maybe movie analysis could be a interesting way of evaluating your IQ performance. Specially in movies like this, you have to be paying attention to every single detail.

nuff said,
take care people
