Use toy cars to see what the scene will look like

Once we've read the script, we bring in the directors and work up some rough sketches. We mess around and will often use a set of toy cars. We position them to see how they'll look on camera - we can enact the stunts with the miniature vehicles.

'It gives us a feel for how the scene will look when we film for real: the angles, how cars will roll, how they'll spin. We try and establish agreement early on between all parties what we are going to do.'
