It often happens that an entire block of campus will be lined with fancy movie-star trailers. I've never seen them filming, but I've seen the prop cars and the trucks with filming permits in their windows.
Yesterday, as I was walking along King's College Circle (where many recognizable shots from The Incredible Hulk were filmed!) when this truck drove by me, cruising at 2 mph:There was a long metal arm extended from the truck, holding a large, fancy camera. I waved right into the lens from a distance of only a few feet, ruining whatever shot they were trying to get. There were two men atop the truck, plugged into headphones and microphones and staring intently at screens. What's getting filmed now? Maybe just stock footage, or second-unit background shots. Maybe my silly smile and overenthusiastic wave will make it into a movie!
