Summer Blockbuster By Weight Of Marketing

On June 26, groups of skydivers will leap from airplanes in carefully synchronized jumps above major cities across the United States to celebrate the impending release of Superman Returns.

"Look! Up in the sky!" skydivers will simultaneously take to the air above Boston, Dallas, Denver, Detroit, Phoenix and San Francisco.

In select cities, the skydiving teams will come together to form a human S shield as they float down to earth. In other cities, the skydivers will carry huge S shield banners, which will be clearly visible from the ground.
