Bu statws perchenogaeth y cymeriad yn bwnc dadl: ceisiodd Siegel a Shuster ddwywaith i erlyn DC Comics am ddychwelyd yr hawliau. Addaswyd y cymeriad mewn [[masnachfraint]] eang o gyfryngau, megis ffilmiau, rhaglenni teledu, a gemau fideo. Portreadir Superman gan nifer o actorion gan gynnwys [[Kirk Alyn]], [[George Reeves]], [[Christopher Reeve]], [[Dean Cain]], [[Tom Welling]], [[Brandon Routh]], [[Henry Cavill]], a [[Tyler Hoechlin]].
