The WandaVision star walked the carpet at Variety's Power of Women gala in Los Angeles on Wednesday, and she spoke with ET's Deidre Behar about the recent rumors that she's been cast in a role on the Game of Thrones prequel series.
"I don't know how things, like rumors like that, get started, and then people think they're legitimate," Olsen said with the laugh.
While Olsen has talked openly about auditioning to pay Khaleesi years ago -- the role that eventually went to Emilia Clarke -- she said she had no idea how the speculation began that she's involved with House of the Dragon.
"Dream casting is fun, yeah, but I heard it was, like, announced though, which is weirder," Olsen said, explaining that several people have told her the casting rumors had been reported as fact. Seeing the record straight the actress said, "I never heard of such a thing."
That being said, Olsen would be happy to be a part of it if something came up.
"I mean, sure, yeah. [I'd like do to] anything that's worth telling, that's a good story, that's innovative, that's great great characters."
