I am a Cinematographer and Director living in Los Angeles with my Wife and Son. I have an overwhelming passion for Photography and Film that bores the hell out of even other Film types.
Why did you take the job if you didn't have a clue as to what it entails? Art Directors hire professionals to do tasks like Costumes (wardrobe), props (propmaster), and location scouting. Sorry to sound pissy, but I'm getting really tired of unprofessional yahoos just taking jobs they're not experienced for, when there are plenty of trained, experienced Art Directors out there trying to get work in their chosen field.
Also, you'd look less like a tool if you just used Google to find out what an Art Director does. I know you have Internet.
In short, no. Come up with something on your own.
I would really consider the meaning of the word "inspired".
Also, that film is just an art piece. It barely has a concept, and if the concept is "OCD", then the filmmaker doesn't know what OCD actually is. So as far as "stealing" a "concept" from this piece, I don't really think there's anything to steal. What, exactly, are you planning on doing with the concept? What appeals to you about this piece?
Well, first of all, I have to say, if I see another film with a Double killing himself, I will go nuts. And I even wrote TWO myself before realizing it's just about the most boring twist someone can come up with.
Having said that...
It's not terrible, it's just... nothing. You don't give us any reward at the end. Isn't it important to the Man in the Mask that the other guy understands WHY he's about to die? What's the point of keeping him alive otherwise? Why can't the man in the mask show his face? What's with the "F" on the desk? Why would he wipe any of the gun off, but not the whole thing? Then why leave it there? Do you know how much forensic evidence he left behind? Why does he let out that little wisp of smoke? Why the blood, which, by the way, he doesn't cough up, he just puts his hand over his mouth, and suddenly blood. And who shot him? Didn't he just kill the guy, who was tied up?
These are not the kinds of questions you want to leave your audience with. Makes things unbelievable.
Don't, don't, DON'T, put your script online for anyone to steal. Jesus...
There's only one MDMA you "take".
NEVER have blood or anything hit the camera lens. It completely pulls people out of the fantasy by reminding them they're watching something filmed and staged. I know, blockbusters (Pacific Rim, Deathly Hallows) have done this, but it looks terrible.
