Laura Siegel Larson talks about her "David and Goliath" struggle over Superman rights.

Laura Siegel Larson, the daughter of Superman co-creator Jerry Siegel and Joanne Siegel, has broken her silence about the long-running legal war with Warner Bros.

She's fought for many years to "terminate" the studio's control of the Man of Steel by exploiting one aspect of copyright law. In 2008, she experienced success when a federal judge in California determined that her termination notice was valid on the first editions of Action Comics that first told Superman's story.
