"Following" is a taut, ingenious British neo noir in which its central character is a seedy young man (Jeremy Theobald) living a marginal existence so severe that he becomes obsessed with the act of following people. The intent is not to do them any harm, but simply to learn about their lives. He tells himself he's gathering material for the writing he plans to do, but what he's really doing is trying to fill up a remarkably empty life.
Inevitably, this young man is caught in the act--by another young man, Cobb (Alex Haw), who's well-dressed, confident and determined to confront his follower. Understandably defensive at first, the young man is astonished to discover in Cobb a man who convinces him that he too is a curiosity-filled follower.
But Cobb is soon taking the young man several steps further, introducing him to the thrills of breaking and entering. Cobb for sure has more sinister motives in mind, but writer-director-cinematographer Christopher Nolan keeps us guessing as to what they finally may be. He also makes you feel increasingly repelled by the duo's systematic, ultimately obscene-seeming invasion of other people's privacy.
Meanwhile, the young man meets a cool, well-dressed blond (Lucy Russell) who has a nicely furnished apartment. She seems to be a no-illusions dame looking out for No. 1--straight out of '40s Hollywood noir. Nolan plays mischievously with the plot he has so deftly set up, moving back and forth in time and mood, alternately revealing and concealing information, as if he were toying with a kaleidoscope. As tension builds steadily we begin to feel ever more keenly that the young man is getting in over his head. But into what and why?
