The Star Wars fandom comprises the community of fans of the Star Wars film series and related media. In some cases, there have been instances of "toxic fandom" within the fan community. Authors Steve Perry and K. W. Jeter have both said they began receiving death threats after contributing works to the franchise. According to Daisy Ridley, when she was being cast for the sequel trilogy, J. J. Abrams warned her that the franchise "is a religion for people." Fan backlash has evidently increased since the release of the Disney films. The fandom is known to pay close attention to obscure characters, and the Internet meme of "Glup Shitto" jokingly refers to eyecatching, but generally poorly known background characters as Wat Tambor, Max Rebo, and Klaud which have gained fan recognition.
