Idea for Opening Sequence of Thriller - 'Stalker'

The opening sequence would start with a slow panning shot of a lamp lit wall. the wall would be covered with pictures of a certain man in different situations, with his family, not knowing he is being photographed, or even smiling and looking innocent. the photos would be in a sort of collage form with writing in pen, such as harmful words and the scribbling out of past lovers, done in a violent way. whilst we are panning, a hand with a marker can appear from beside the camera and write on the wall, or scribble out another character in a photo beside the man. the names of the directors and team behind it would feature at random points throughout the collage. then the diagetic contrapuntal music would pass over a cut to a woman walking down an office corridor. we would have a tracking shot following her smart high heeled shoes in a side on angle. another cut to her finger pressing a button on a lift and then a quick cut to a long shot of her. as this cut happens the music stops and the lift opens, revealing the man we have seen so much of on her wall at home, as she stands next to him she says 'going up?' and the doors close, finishing the opening sequence.

                     I like this idea as by the time the collage ends, the audience knows a lot of information about this victim of a stalker, that he has a wife and children for example. Anything we see in these photos we will remember about this man, we can even guess what his personality would be like from pictures of him with friends or in a bar or club. But, we know nothing about the stalker apart from the fact that she works with the man in an office. The end part of the sequence leaves the audience guessing as to what will happen next in the lift, a cliff hanger. And for the time the two people are in the lift together, the sense of suspense and terror would be overwhelming. The fact that we know something that the man does not know is the key idea of the sequence, which I believe works well.
