Filming "National Treasure: Book of Secrets" in DC Video

This was outside my office building earlier today. It's the movie "National Treasure: Book of Secrets", a sequel to some other movie I didn't see. They were filming on 16th street between H and I streets most of the day today (mar. 29, 2007), and I caught this particular video at about 5:30pm. according to IMDB, the guy who was in front of the car (I think i was filming while they were filming) is Justin Bartha playing the character of Riley Poole. the buildings on this block of DC are the Motion Picture Association of America (Washington office), the AFL-CIO and the Hay-Adams (posh hotel). the White House is in the background about a block away.
