This is really, really impressive.
Read about the making of the spot.
The take that you have seen is the very last take we did at 8pm on the last day of the shoot. Take 40. The tension as we watched Robert do this take was unbelievable. It was such a good take at every stage and so the longer it went on without any fluffs the greater the pressure grew for nothing to go wrong. When he got to the end and I got to call cut there was this huge roar and applause from the crew and agency and I knew we had it.
