ILM VFX supervisor Craig Hammack compared this work to his time on Tomorrowland (2015), but noted the additional challenge of not just building a futuristic city, but also one that was culturally appropriate. He explained that African culture has a "certain amount of earthy material qualities that make things difficult to design as a futuristic city," which would typically use much steel and glass. ILM looked to real life examples that blend modern architecture with natural environments like One Central Park in Sydney and The Pearl of Africa Hotel in Kampala, but also had to "depart from a strict understanding of physics and go into a movie cheat world" at times to produce the desired look.
