The Marvel star recently set the record straight on speculation surrounding her casting in the fantasy series.
Fans will be disappointed to learn that Olsen – best known for her Emmy nominated performance as Wanda Maximoff in WandaVision – will not be making an appearance on the hit HBO programme anytime soon.
“I don’t know how things, rumours like that, get started – and then people think they’re legitimate,” Olsen told Entertainment Tonight.
“Dream casting is fun, yeah, but I heard it was, like, announced, though, which is weirder,” she added.
People informed the actor that the rumours began to circulate seemingly due to a post on an unverified pop culture Twitter account shared on 4 September.
“I never heard of such a thing,” said Olsen, 33.
The actor said, however, that she would be open to starring in House of the Dragon if the producers were interested.
“I mean, sure, yeah. [I like to do] anything that’s worth telling, that’s a good story, that’s innovative, that [has] great characters,” she said.
Olsen previously auditioned for Game of Thrones, reading for the part of Daenerys Targaryen, which went to Emilia Clarke.
Olsen recalled: “I auditioned for Game of Thrones. I auditioned for, like, the assistant to the casting director in a small room in New York with just a camera on me and them reading the script.
“I was doing the Khaleesi speech when she comes out of the fire. It was awful. I didn’t get a callback.”
