During the development of the project the directors and producers met with some of the world's best Parkour practitioners. The directors were given exclusive training in gym sections to help them fully understand Parkour.
The production took over three entire levels of the car park. These levels were provided completely empty and so had to be filled with cars.
The production sourced over 50 cars to be used in shot. Every car that is in the final film was sourced by the production (apart from the title sequence).
There were three cameras on set - two Arri SR3s (standard professional Super 16mm cameras) and an Aton Minima. The Minima is a Super 16mm camera that is far smaller and lighter than the normal cameras.
