Zainab Fagge has chosen three locations in London to film a 2 minute opening sequence depicting a stalking. The first location is a busy street where long shots will establish the characters. The second is a park, chosen because it is normally a safe place but can be dangerous at night. The third is a side road near the park where an extreme close-up will show a character peeking behind a wall while the stalker stands in the background. Additional locations include under a bridge and again in the park for the climax.
