As you've probably realised by now, we eventually gave up on the sequins and wires. We spent ages working out how it was all going to come together; how the wires would be animated and raised up when the camera came past. We even briefly toyed with some mirrors and prisms in an effort to get the camera lens lower to the ground. We also considered building the entire set on a false floor that we could remove as the camera moved along, allowing us to get really low to the ground. This seemed like too much work, though, and would have really shook the set.
We also had to think about the final bit of this scene, where the last bullet flies into the camera.
