Before starting High-Rise, I was staying one summer in a beach high-rise at Rosas on the Costa Brava, not far from Dalí’s home at Port Lligat, and I noticed that one of the French ground-floor tenants, driven to a fury by cigarette butts thrown down from the upper floors, began to patrol the beach and photograph the offenders with a zoom lens. He then pinned the photos to a notice board in the foyer of the block. A very curious exhibition, which I took to be another green light to my imagination.
