That when Garfield sets up the camera in the class room & has a conversation with the main gangster that it shows close ups of the actors faces through the point of view of the camera?? The camera was mounted so who the heck was filming with the camera? lol. I checked in the plot hole section and didnt find anything about this.
I noticed that too! :-) I'm thinking that the close-ups were just to emphasize the fact that Cesar did steal the watch (you can look directly in his face). It also zooms in on Garfield's watch, emphasizing that he found it and now has a way to prove that Cesar stole it (the video camera). I don't think the close-ups were meant to be taken literally, rather, they were to be taken symbolically. It seems that this film incorporates a lot of symbolism (such as when Garfield enters the wrong classroom and begins teaching, his 'view' of the students is initially blurry because of his fear of teaching again after having been stabbed).
I agree, though, that when I first saw the whole camera scene, I was wondering why the heck they were doing the zoom-ins. I think it was meant for artistic symbolism. I could be wrong, though :-P This is just my take on it. Hope it helps!
People, that was just a visual style. The movie has lots of these moments. It was not suposed to be seen "literally". They used the Video-Look to describe the intensity using the camera as a "witness". There were no "two" camera setups.
