Walking shots and potential argument scene

this is a shot from The Verve's bittersweet symphony promotional video. the protagonist is walking down the street bumping into people and vacantly ignoring them whilst they look in disgust.

in that scene, a woman follows and shouts to him, but he continues to walk and blatantly ignore her, not even looking to acknowledge her. this is an idea we could use for our video, since the protagonist knows something is so wrong but has had his memory erased, meaning he cannot identify the problem. the idea that he is so disturbed by a missing piece of information is what drives the protagonists characteristics, and he is so confused he refuses to acknowledge anything outside of his thoughts. the problem with a shot like this is that we are already on a tight schedule, and it would be harder to film in many respects. However, we are intent on having someone turn around and shout and make a fuss when the protagonist bumps into them, but they will just fade into the background rather than play a larger part like the woman in the clip.
