“During the course of the movie, watch the LED signal strength indicator lights on the brothers' CB radio. The first four indicator lights change colors in nearly every scene, including bright green, dark green, yellow, red, and crimson. This is obviously intentional and not a series of continuity errors.”
First off, this is completely untrue as the photos show...
1. First Contact with Rusty Nail (~11:00)
2. The Hotel (~17:00)
3. “You should really get that fixed…Your taillight.” (~32:00)
4. Apologize as Car is Crushed (~45:00)
5. Look…in…the…trunk…Lewis (~1:00:00)
6. Corn Scene (~1:15:00)
Yeah, um...I don't see the first four colors changing from anything but yellow.
Now, even if this were true, what is the point of submitting this bit of trivia? After all, even if this person was correct, is there ANY visual theme, image or motif that is NOT intentional? We can look at the close-up of the CB radio as being no different than a close-up of a face; emphasizing the importance in both detail and attention. Like the mask motif in slasher films, the CB Radio is acting as a mask but through taking on a different form. For instance, while we see the white mask of Michael Meyers who's the killer, we hear/see the CB radio of Rusty Nail who's also the killer.
And if a director is going to use one of the most significant and important aesthetic film techniques – the close up – would there EVER be a case where a noticeable visual change is not intentional? I’m not talking about obscure ultra low-budget movies where the amateur production values can lead to strong continuity errors. I’m discussing professionally directed and produced films. Whoever made this comment might as well go through the work of all great film auteurs, stating that their choice toward changing visuals is definitely "intentional.” But maybe not, because as the photos demonstrate he was completely wrong in the first place.
