There is absolutely no evidence that Han Solo: A Star Wars Story is casting Sana Solo, except that in the comics she is depicted as a black woman.
Some even speculated that Han Solo: A Star Wars Story, which takes place a decade before A New Hope, wouldn’t have time to introduce a love interest.
We know that Han Solo didn’t meet Princess Leia until Star Wars: A New Hope, so some assumed that the notorious Space Pirate was living the swinging single life up until that point.
It isn’t known when shooting will being on the young Han Solo movie, which has a May 25, 2018 release date.
