Concept and Vision

This past week i've been working on my Director's Notebook, completing the drafted version of the first two parts. I've managed to come up with lots of ideas for my vision, and i've finally decided on a concept: "Lies are a handmade dress to keep us safely covered from the cruel reality".

Personally i feel quite confident on how my work is turning out, yet i'm not sure how will i ever manage to finish it in time. I think that there's so much to write, and i have so many ideas, but i'm not sure how or when will i include them all into it.
Something that has been bothering me is the fact that i have literally millions of ideas for both scenes, and even for the entire play as a whole, and as much as i would like to include them all, it's pretty much impossible. I mean, i've had trouble on focusing a main vision, because of all the new cool ideas that i come up with. So i'm constantly struggling with focusing my ideas and scratching the ones that won't work, because i really have a lot of expectations. The good thing though, is that the work is never truly staged (except for our sampling of it), so it gives lots of space for me to actually include the craziest and coolest ideas for my vision, because it will never be physically done, and no one will have to pay for it (relaz cino...).
In terms of my concept, i found it pretty easy to come up with. From the beginning i perceived the play as a game of lies, and a struggle with reality, so i already knew what i wanted to say with this play. The hard part for me was actually phrasing it, because i sometimes want it to sound poetic, but it's supposed to be as simple as possible.
Now that i do have a concretely phrased concept, i'm confident i can move on with my work, and i can focus more my ideas directed towards it.

Something realli important i learned is that you always need to think about what you want your audience to feel, and later talk about over coffee after the play. Like Brecht himself proposed: the audience must feel a sort of catharsis through the self reflection of the actions in the play. And that's pretty much where i want to get. I want my audience to experience the play in Blanche's shoes, giving them the experience of social injustice and insanity. It is important for a theatre maker to think about this as a starting point, specially if he doens't have a fully fleshed concept at hand. I think it helps a lot to narrow down, until you actually get to phrase it. Plus, it also helps you focus on your vision to use the best ideas that fit both of these thoughts.
I think that putting yourself in the audience's perspective helps a lot when it comes to your intended impact on the audience and concept. It pretty much helps you identify and evaluate your concept and vision and whether it works or not. Maybe you had a lot of cool ideas, but if you see it from the audience's point of view, they have nothing to do with your concept, and they don't create the effect that you wanted. In my case, i'm still drafting my ideas, though i'm pretty close to a concrete scene, so i can't evaluate like that yet. But in the case of my vision, i can do this to see if my ideas are too crazy and unrelated, or if they do achieve what i want.
As i mentioned before, my concept is about lies covering up reality, and i chose it because i wanted to talk about Blanche's constant lying in order to walk away from the truth and reality for what it truly is. And i think most people do it, and so we make our own pretty lies and fantasies that cover up what we don't want to see or hear from reality. So i wanted the audience to reflect upon the lies we tell and create ourselves in order to escape the cruelty of our own reality. And thus comes my vision of the audience looking at the play through Blanche's perspective, experiencing everything like her. And as a theatre maker/producer/director, i must make sure to use every possible element to achieve them. For example i will use annoying sounds to begin the play, so the audience feels as stranged as Blanche felt when she got to Elysian Fields. It is important for a director to take notes on the most minimal details to reach his objective. To always be sure that things have a purpose in the scene, rather than just filling it up. Obviously, he needs to direct everything towards his vision and concept in order to reach the effect he wants.
But something i have been wondering about is how director's manage to translate the playwright's meaning into the concept? I mean, the director obviously has a concept that matches the play, but many elements the playwright included may affect negatively the director's vision. Should he take them out? Wouldn't it loose a bit of meaning? What if i changed the cue for the Varsouivianna to enter? Would it change Williams' effect?
