World Wide Crazy News!

Warning: If this is true, this post contains spoilers. But if this isn't the stunt crew for Iron Man 3, the only other explanation would be Cirque du Soleil.

According to Superhero Hype:

Several people were dangling from cables over the Cape Fear River Friday. The production of Iron Man 3 is expected to film scenes in that area next week and it looks like this stunt could be part of the crew preparing for some special effects.

Cape Fear River travels almost the entire length of North Carolina, which is where Marvel is rumored to be filming, so it seems plausible.
