The duo spent the better part of their lives unsuccessfully trying to reclaim some part of their creation, only to be rebuffed time and time again. While DC raked in billions from Superman alone, Siegel and Shuster lived the lives of paupers. They were given a yearly pension in the late 1970s by Warner Bros. (which had purchased DC), but only because the studio couldn't afford the bad publicity with a Superman movie on the way.
"You're right, scrapping the costume is not going to help. Just pay them."
In 1999, three years after Siegel died, his family successfully won the rights to his half of his creation. A happy ending, right? Nope! This meant dick to Warner Bros., who still refused to pay them a penny, leaving them to fight in court for another 10 fucking years. And the superdickery continues: More recently, documents disappeared from Siegel's daughter's attorney's office and somehow wound up in the hands of Warner Bros. executives.
