Dear Mr. Anderson: Why do most shots in this film have a slight tilt to the side? Mistake?

Rating: 9/10 (26 May 2012)

Dear Mr. Wes Anderson, Firstly, thank you. What a sweet, beautiful film you have (yet again) created. I will remark that this is the most "Wes Anderson" of your films; you have further cemented your own private genre. The characters was touching, the film was inspiring. Thank you.
That said, I have a bone to pick. I noticed that about 90% of the shots in this film have a slight tilt to them. And additionally, most of that 90%, the tilt is to the right. What I mean is, if you are looking at the horizon line in a given shot, the horizon on the right is slightly higher than the horizon on the left. It's not the case for the entire film... but it is the case for most of it.
What's the deal? At first I thought it was a projection issue where I saw it last night at Arclight Hollywood. Or maybe it was my perspective in the theater (theater-right). But then, upon returning home after thoroughly enjoying your film, I watched the trailer on my computer to confirm or deny my theory. And alas, in most of the shots, I see there is a subtle tilt to the right (though it's harder to notice on a smaller screen). It is most notable when there are man-made structures involved. Such as fences or banisters or walls where you can see the edges.
What happened here? For someone who so carefully stages his scenes in a highly symmetrical fashion, I was shocked to discover this imperfection(?). I can't say it removed me from the film: it didn't. I was mesmerized by the story. However, it was like a subtle itch that never went away during the duration of the viewing.
I'm guessing this mistake was result of a preoccupied camera operator / steadicam operator with a subconscious bias to the left. And that such mistakes would be difficult to catch on playback monitors on set. However, I find it hard to believe that this issue was not spotted in the viewing of dailies. I am curious to see if you have a response to this. If do, I would appreciate it greatly if you submitted said response to blakekhodges(at) gmail.com - my email.
Again, I was once again extremely pleased with the film you have given the world. I expect I will be viewing the film again and again, and recommending it to more of my friends. As for the shot-tilt, we can't expect every film to be technically perfect, although, considering your aesthetic style, I almost do. Anyhow. Thank you again, and please keep up the great work. If you're ever back in LA from your travels, feel free to drop me a line and we will grab a delicious coffee. Thank you.
Sincerely, Blake
P.S. If, for your next film, you decided you'd like to try and broaden your style palette, I would not be opposed.
