Little to report again. I can confirm that the shooting alias is 'Magnus Rex' as this appears on the lanyards of the crew. A fan (Lauren James) who had been here all day yesterday heard from a staff member that something 'interesting' was to be filmed today at lunchtime. (Since I have a real job to go to, I was unable to hang around to see if this was going to be true!) She did also spot Christopher Nolan a couple of times yesterday.
Today The outside lighting rig on the scaffold/cherry picker was back on
I also noticed a US car on Charterhouse Sqaure, with the technical trucks. It was a dark grey Grand Marquis LS Mercury.
