Knowing the distress that filming can place on a city, Joss Whedon took to the Internet to issue an apology to the people of Seoul, South Korea for the inconveniences that will take place during the filming of Avengers: Age of Ultron. Buildings and bridges will be shut down starting on March 30th so Cap and Thor can run around in tights and fight guys in mocap suits, and Whedon says he's sorry in advance.
The most interesting part of this video seems to be that he stopped in the middle of a construction site. Debris and cranes and stuff are all around him, adding to the tension that maybe, just maybe, the Hulk will run through the background and put our favorite director/writer in jeopardy. Spoilers: Nope.
