CHICAGO (AP) — A nonprofit group has filed an updated complaint in federal court as part of its efforts to keep filmmaker George Lucas from building a museum along Lake Michigan in Chicago.

The Chicago Tribune reports (http://trib.in/1PYAsf6 ) that Friends of the Parks' filing Friday focuses on a ground lease agreement that the Chicago Park District has signed with the Lucas Museum of Narrative Art. The agreement gives the Lucas museum a 99-year lease on the lakefront property for $10.

A judge ordered the group to file an amended complaint because the museum recently released revised plans that include more green space and a scaled-back design.

Mayor Rahm Emanuel offered the land along Lake Michigan for the project to the "Star Wars" creator, who chose to build in Chicago over San Francisco.
