I was at the Naval College at Greenwich on Monday and took the following Videos & Photos. The main scene being shot today was of Thor running up and down a central London street (believed to be Charing Cross as 2nd unit filming was shot there earlier this month) after an event that causes the traffic to come to an abrupt halt and passengers running away. Also Thor coming out of the underground station leading out passengers to the street and then being met with Jane Foster (Natalie Portman) carrying a gadget of some sort.
I managed to find a position where I was able to view actual filming of the day on a monitor.
