What Was the Last Avengers Scene Filmed in Cleveland?

The Plain Dealer has reported on the last night of filming for Joss Whedon's The Avengers in Cleveland. The newspaper's description is spoilerish, so only read on if you don't mind knowing what a specific scene entails this early:

FitzGerald said the scenes being shot inside the 99-year-old courthouse are the interior version of the scenes that tie into what was shot last week on Public Square where hundreds of extras ran in terror from Tower City.

The scene is a ball with many people in formal wear, he said. There is an altar that looks Egyptian where a fight between (evil Norse god Loki) and one of the heroes will occur, he said.

The film will be shot until 5 a.m. Tuesday when the crew will pack up and drive to New York City for a quick shooting of a few scenes.

And here are some extra bits from the newspaper:

Scarlett Johansson filmed scenes at an old warehouse on Ashland Road near Longfellow Avenue, off Cedar Road near the Norfolk Southern railroad tracks Friday and Saturday.

This afternoon another scene of destruction was filmed on Walnut Avenue at East Ninth Street. A bus and a taxi were crushed by a huge chunk of building outside a fictitious Bed, Bath and Beyond.

Robert Downey Jr., Chris Evans, Mark Ruffalo, Chris Hemsworth, Scarlett Johansson, Jeremy Renner, Tom Hiddleston, Stellan Skarsgård and Samuel L. Jackson star in the May 4, 2012 release.
