"Star Wars" is a growing brand with the upcoming "Han Solo" movie, and "Rogue One: A Star Wars Story" further expanding the popular franchise. The "Han Solo" film is still in early stages of development, but it is already shaping up to meet the high standards of Lucasfilm and Disney, with Emilia Clarke now joining the cast.

Fans will recall that Clarke is already becoming a household name. She is most well-known for portraying Daenerys Targaryen on the hit HBO show "Game of Thrones." She has not restricted herself to the fantasy series, however, as she did play Sarah Conner in "Terminatory: Genisys" and the lead role in "Me Before You."

"Clarke's role will round out a dynamic cast of characters that Han and Chewie will encounter on their adventures," reads the official announcement from the "Star Wars" website.

She will be joining Alden Ehrenreich and Donald Glover, who will play Han Solo and Lando Calrissian respectively. Chewbacca is also confirmed to be in the film, which will tackle how Han won the Millenium Falcon from Lando and how Chewbacca came to be the ship's first mate.

Unfortunately, the details of her role are still unknown. Given that this is a prequel showcasing the early years of Han Solo, Chewbacca, and Lando Calrissian, it is possible she will portray Han's love interest before he ended up taking the Millenium Falcon and falling in love with Princess Leia Organa (Carrie Fisher).

The Hollywood Reporter further reveals that "Power Rangers" movie star Naomi Scott, "Creed" star Tessa Thompson, and "Emerald City" star Adria Arjona were all running for the role. This will be Clarke's biggest franchise yet, even bigger than the "Terminator" series, and likely her next big role following the end of "Game of Thrones" since it only has two seasons left.

The stand-alone "Han Solo" movie is expected to premiere in 2018.
