Warning: Spoilers
Filming on Spider-Man 3 recently hit Los Angeles and a source for Ain't It Cool News filed this report that may preview one part of the film:
"My friend in Los Angeles said that Spider-Man 3 has already begun shooting second unit photog, specifically near spring and 5th. Much like when Spider-Man 2 was filming in November 2002 in Chicago on the train tracks [for plates], that scene had to be filmed at the forefront because it was the centerpiece of the movie and took the ENTIRE production, from filming all the way to post, to finish animating. I assume the same is for here but nothing major is going on at the moment. Just some cops and SWAT teams firing gas grenades at a building. Some Daily Bugle paper machines scattered throughout the streets and some fake subway stations. Most of the shooting he said was done at night. No words on Flint Marko or Mr. Brock showing up. He said it looks kind of like the area where Madison Square Garden/Penn Station is."
