Coinciding with the 10th anniversary of the World Trade Center attacks, Steven Spielberg is executive-producing an in-depth documentary about the rebuilding of the site for Discovery's Science Channel, set to air in 2011.

The project, 'Rebuilding Ground Zero,' will focus on the engineering and construction of One World Trade Center, the 1,776-foot skyscraper formerly known as Freedom Tower; as well as the memorials, park, underground museum and transportation hub being erected at the site. It will also pay tribute to those who died on Sept.11 and examine how the rebuilding is affecting the lives of everyday New Yorkers.

New York Mayor Michael Bloomberg called the effort "a compelling story of remembrance and renewal," according to the Science Channel. "The fact that Steven Spielberg -- one of the great filmmakers of our time -- will produce a documentary on it ensures that the story will be brought to life for people around the world for generations to come."
