Much-maligned plans for a massive, spaceship-like museum built to house filmmaker George Lucas's art and memorabilia collection have been revised. The new design was revealed in federal court Thursday as part of proceedings for a nonprofit group's lawsuit to halt the construction of the Lucas Museum of Narrative Art on Chicago's waterfront.

The group Friends of the Park wants the land overlooking Lake Michigan, currently parking lots, to remain open. They have three weeks to fine-tune their complaint now that the architect's new plans were unveiled.

Although a fresh rendering was not provided to press, some 400,000 square feet are said to have been trimmed down to "up to" 300,000 square feet in the new plans. More green space was added including a garden, eco-park, dune field and prairie area to host arts and film events.
