48 hours to save the world - update 4

OK, it's half past five. Have been across London and back to deliver cgi sequences and help with the editing, although how much "help" I can be at this point may be unclear. Curiously, although there were about 100 teams at the briefing, we didn't run into any others during our location shoots yesterday night or this morning. I'm looking forward to seeing what other teams got up to.
