Daenerys Targaryen [SEP] Casting and development
Martin said that the character was portrayed as older in the television series than her literary counterpart because of child pornography laws. Daenerys was originally played by Tamzin Merchant in the pilot episode. After negative reception at private viewings, HBO ordered the pilot to be reshot and recast. Clarke was recast as Daenerys after an audition in 2010. Weiss and Benioff said, "Emilia was the only person we saw—and we saw hundreds—who could carry the full range that Daenerys required". Clarke said that the role of Daenerys was "not your typical bonnet duty that you have to go through as a young British actress".
