Well, it is The Avengers -- what did you think was going to happen!
Check out a short video from dowtown Cleveland where Joss Whedon is shooting The Avengers.
We see what looks like pieces of a building fallen on top of crushed automobiles.
Most likely this is a result of either Thor or Iron Man battling some evil doer (as they can both fly) - or each other!
Might as well add the Hulk, too!
The Avengers assembles May 4th, 2012 and is directed by Joss Whedon, starring Robert Downey Jr. as Iron Man, Chris Hemsworth as Thor, Chris Evans as Captain America, Samuel L. Jackson as Nick Fury, Mark Ruffalo as the Hulk, Scarlett Johansson as the Black Widow and Jeremy Renner as Hawkeye.
