Here are the Catching Fire trailers in Oakland, New Jersey. Sorry the photo isn’t more quality. There was nowhere to park on that road so we could only drive by. If we stopped they wouldn’t have let us walk over anyway.
From what I saw, The trailers were on the side of the road and next to a path that leads into the woods, where I assume they were filming. A spokesman confirmed that the production got approval to film there for two days this week. According to an inside source, they are filming additional scenes and taking photography for Catching Fire (not really sure what that means, possibly promotional images?)
