The first creative challenge was to get the design and creation of the robots right. We initially worked with a concept artist, to come up with the designs for the robots, which we then sent to our VFX partners who built greyscale models so that we could explore rigging and features. By utilising an anatomical intelligence that allows not only their limbs to manoeuvre in creative smart ways but the plates that form their shell or armour to shift and tilt when needed, it enabled us to heighten an emotional reaction but also signify language between them, which also allowed us to craft a sense and range of performance.We had to ensure that we set the tone and created an atmosphere that our audience could buy into. We decided that the more tension we create, the more satisfying the release is when we see the robots go for the car.
