Victory in ritual combat comes by yield or death.
The look of Warrior Falls was created by multiple locations, reference footage, and a physical set outside Atlanta. These include the Iguazu Waterfalls in Argentina, on the border of Brazil, which provided reference for Warrior Falls; Jim Jim Falls in Australia’s Northwest Territory which provided reference to the artists making the rocks for the Warrior Falls set, according to Cinefex #158; and Victoria Falls in Zambia (on the Zimbabwe border) was used when the Royal Talon fighter flies by Warrior Falls, according to production designer Hannah Beachler on a ComicBook.com article.
Finally, for shots of the actors battling in the water at the base of the Falls, a physical set was constructed behind OFS Fitel, in Norcross, GA–a location that has been getting use since Captain America: Civil War. This set can be seen on Google Earth from the Nov. 2016 and Mar. 2017 satellite imagery.
