During this period, the documentarian filmed interviews, started editing, and completed tasks like the crew list. They then finished their shot list, which helped them feel more prepared and confident in production. Subsequently, they filmed cutaway footage in London locations and edited what they had so far. Additional cutaway footage was later obtained and edited in. Voiceover audio was also rerecorded and inserted. More original cutaway footage was acquired as requested. Voxpops and an interview were then reedited and included in the documentary.
