J.J. Abrams gave 'Star Wars' fever a major boost by revealing his cast of principal characters, but other rumors suggest a "substantial role" is yet to be announced.
The unannounced addition would be for a female role, according to sources speaking to The Hollywood Reporter.
Daisy Ridley was one of several surprise choices detailed by Abrams in an 29 April announcement, along with CGI virtuoso Andy Serkis and experienced stage and screen actor Max von Sydow.
But previous rumors had indicated that Lupita Nyong'o, breakthrough Oscar winner of '12 Years a Slave', and British theatrical actress Maisie Richardson-Sellers had been in negotiations with Abrams and his representatives.
The Disney project was thought to have been looking for a "mixed-race female in her 20s."
None of the 13 announced cast members had been linked with specific roles, though the young trio of Domhnall Gleeson, Daisy Ridley and John Boyega are likely to comprise the film's trio of new heroes.
Prior to the announcement, Adam Driver had been rumored to play the film's antagonist, with Oscar Isaac's name surfacing not long before official word on the matter.
Original trilogy stars Mark Hamill, Carrie Fisher and Harrison Ford are expected to reprise their roles, alongside supporting actors Anthony Daniels, Peter Mayhew and Kenny Baker.
