Standing on the very tip of the 828m building, Smith-Ludvik had an area of just 38cm to place her feet on for the five hours of filming that took place.
A custom platform with an attached pole was built at the top for Smith-Ludvik to stand on. She was attached to the pole as well as two other points on the pinnacle through a hidden harness under the Emirates uniform.
Filming started at sunrise to catch the golden hour light so the production team, including Smith-Ludvik, began their ascent to the pinnacle before dawn. The climb took an hour and 15 minutes from level 160 of the Burj Khalifa, and the team had to scale several tiers and ladders inside a tube to reach the top.
