Today we filmed the government briefing scenes in the council chamber of Hereford Town Hall. It took ages to get going, as it proved extremely difficult to find a general’s uniform for the Chief of Defence Staff to wear. Then Johnny Cartwright, portraying scientific advisor Benton, had trouble with his Star Trek-challenging technobabble lines, which led to elaborate arrangements of cue cards around the room. By the time we finished the first scene of the day, we were about 2 hours behind scehdule, and we absolutely had to be out of the chamber by 6pm. Somehow – I guess the only possible explanation is my own unwavering genius – we recovered and wrapped by 5:45pm. Though it was 6:15 by the time we’d moved all the gear out.
