The radio [[Wikipedia:|serials]] were made with the full co-operation of George Lucas, who for one dollar each sold the rights to KUSC-FM, the public radio affiliate at his alma mater, the University of Southern California. Lucas also allowed the use of original sound effects and music from the films. The adaptations for radio are part of Star Wars canon within its Expanded Universe. National Public Radio has no plans to produce radio dramatizations of any other Star Wars films.
