This was another mission impossible from the Case crew. We shook hands with Director General of the Ministry of Tourism in Berlin on a Wednesday and were filming from a helicopter atop a mountain two day later on Friday. We were late in the season to catch the snow, so had to follow where in the country there would be snowfall and react very quickly to mobilise and shoot the scenes needed. Having started late March we wrapped mid April and delivered early May. Great achievement by any standards.
