Sources tell The Hollywood Reporter that Abrams is still searching for another female lead alongside Daisy Ridley. That makes a lot of sense, as Ridley was the only woman in the list of new cast members, including John Boyega, Adam Driver, Oscar Isaacs, and Max von Sydow. (Carrie Fisher will be reprising her role as Princess Leia.)
THR had earlier reported that Abrams wanted to find a mixed-race actress in her 20s and noted that the director met with Oscar nominee Lupita Nyong'o a few months ago. And as we noted when the cast announcement came out, Maisie Richardson-Sellers wasn't part of it, but has been rumored to be up for a role.
We'll find out soon enough as filming begins this month. "Star Wars: Episode VII" is due in theaters December 2015.
