subtle 6 digit number provides insight into depth of the film

Rating: 9/10 (24 July 2006)

This film was recommended to me by a friend who has a taste for certain great films of a dark, foreboding quality, that, however, DO ask the hard questions and pose scenarios with plausible outcomes that leave one hanging on to the movie. Films that leave a piece of themselves in your mind, make an impression, and even make you think...these are the films I appreciate most. This is what I appreciate about The Machinist.
I had seen part of the film about a month ago, but I only watched about 20 minutes (in the middle of the movie), then stopped lest I ruin it for myself. I am curious if anyone else has picked up on this one thing, as i'm sure other's have but just haven't voiced it or i haven't found it in writing.
We all know that Trevor Reznik's world and perception of reality have been twisted. In particular, the scene in which he is following the red comaro through the tunnel, squinting to try to identify the license plate numbers, he reads to himself aloud "743 CRN". Staring off into space, concentrating so the plate number will remain etched into his mind, he veers from his lane, almost hitting another driver. After he swerves to miss this driver, he comes to a stop on the side of the road. In this shot we see the front of his car coming to a halt. In this moment you can catch a glimpse of the front license plate of the white truck he is driving. The license plate number reads "NRC 347".
This plate number is the exact opposite of that on the red camaro he is following. Later on, the viewer discovers that the red camaro is his own car. So in the twisted reality of Trevor Reznik, the backward license plate number can represent his skewed perception of the red camaro, of the other driver so called "Ivan", and most importantly represent the skewed perception of his reality, everything about him, the way he is perceiving these events, or more importantly the role of the people in these events.
This makes me wonder what other minute, quick, subtle details are also in the film. I have read the popular comment on elements of Dostoyevsky in The Machinist, and I'm sure, upon another viewing, I would catch some of those and then some more, hopefully.
That's just a few thoughts of mine on the film. I absolutely loved it and plan on purchasing it. But I was just wondering if anyone had caught the license plate number on Trevor's white truck and realized the connection?
