Curtis chose Notting Hill as he lived there and knew the area, saying "Notting Hill is a melting pot and the perfect place to set a film". This left the producers to film in a heavily populated area. Kenworthy noted "Early on, we toyed with the idea of building a huge exterior set. That way we would have more control, because we were worried about having Roberts and Grant on public streets where we could get thousands of onlookers." In the end they decided to film in the streets. Michell was worried "that Hugh and Julia were going to turn up on the first day of shooting on Portobello Road, and there would be gridlock and we would be surrounded by thousands of people and paparazzi photographers who would prevent us from shooting". The location team and security personnel prevented this, as well as preventing problems the presence of a film crew might have caused the residents of Notting Hill, who Michell believes were "genuinely excited" about the film. Location manager Sue Quinn described finding locations and getting permission to film as "a mammoth task". Quinn and the rest of her team had to write to thousands of people in the area, promising to donate to each person's favourite charity, resulting in 200 charities receiving money.
