The cars were based on production Computer Aided Designs provided by BMW, which we then optimised for creative use. The breadth and depth of our creative ideas meant we pushed the models to their limits in digital design and animation programmes C4D and Houdini; experimenting with lots of different ideas and techniques. Once concepts were finalised, we went through several rounds of product correctness to ensure the cars looked 100% accurate.

We also filmed a live-action bulldog which was compositted into the films using Nuke & Flame; the live props being swapped for our CGI objects.

Finally, there was an extensive period in 3D compositing programme Flame, using cryptomattes to retouch all elements of the car.
