Originally released as “Down“, it’s a movie about the “tallest building in the world” and its killer elevator shaft. It was filmed in early 2001 and there are a few shots with the World Trade Center in the background. The movie was never seen in US theaters because the scheduled release date was after 9/11/01 and no one had the stomach for a flick featuring a decapitating elevator. It was released to video two years later.
