From This is London
Five pictures from the Vendetta movie shoot in London this past week.
The pictures are actually part of This Is London's brief news article about the filming
According to the article, the film needed permission of 14 government agencies to film in front of Parliament, and filming lasted 'till about 4:00 in the morning. The caption to one of the pictures calls this one of the largest location shoots in London in years.
Armchair reporting from my computer, my guess is that this shoot was for the finale of the movie when the people riot and the Nazi/Norsefire dictatorship collapses. That one of the pictures includes a crowd of people in cloaks and Guy Fawkes masks seems to confirm the Ain't It Cool article I mentioned earlier this week.
My thanks to Warren Hoss Jr. for this info.
