This unassuming office building is one of the filming locations for the Superman movie coming out in 2013. It's also super green: it was the first project to be certified LEED-CS Gold.
Superman can leap "the tallest building in a single bound", quite a feat at the Willis Tower, which is 1,450 feet (443 meters) high or 1,730 feet (520 meters) including the twin antenna towers.
