"The wigs are hard," Smith, 41, admitted, and Glynn-Carney, who plays Aegon, agreed, naming the "wigs, the bald caps [and] the pins" required for the signature platinum Targaryen hair among the challenges. What's worse is that Smith has learned there's potentially a better way for him to transform into Daemon.

Matt Smith told audiences at New York Comic-Con that he hadn't "heard a thing" about "House of the Dragon" season three. Season two wrapped up in August with a finale widely regarded as muted because it focused on the emotional development of its characters rather than a fight scene or dramatic death.

"I've not heard hide nor hair," Smith, who plays Daemon Targaryen, said when Josh Horowitz asked if any of the stars had seen a script or heard rumblings about what's to come. "I've not heard a thing," he reiterated, before asking if Glynn-Carney, 29, or Frankel, 30, had.
