Disney+'s live-action Star Wars television series based on Rogue One's Cassian Andor has officially added four new actors to its cast, including Genevieve O'Reilly -- who played Rebel Alliance leader-to-be Mon Mothma in 2005's Revenge of the Sith.
As announced by StarWars.com, O'Reilly will reprise her role as Mon Mothma opposite Diego Luna's Cassian Andor in the upcoming series. Originally played by Caroline Blakiston, Mon Mothma made her first big screen appearance in 1983's Return of the Jedi, with O'Reilly stepping up to play a younger version of the character in Revenge of the Sith. Though all of her speaking scenes were cut from the Prequel Trilogy's final film, O'Reilly went on to reprise the role in 2016's Rogue One: A Star Wars Story.
As far as the Cassian Andor series goes, O'Reilly is joined by fellow official new additions Stellan Skarsgård (Pirates of the Caribbean: At World's End, Good Will Hunting), Denise Gough (Collett, Angels in America) and Kyle Soller (Anna Karenina, The Titan). That being said, no official details regarding Skarsgård, Gough and Soller's roles have been made available at this time.
Described as a "spy thriller," Disney+'s Cassian Andor series follows the Rebel operative five years before the events of Rogue One. That film's co-writer, Tony Gilroy, will serve as showrunner, writer and director on the series. Other writers include Nightcrawler's Dan Gilroy, House of Cards' Beau Willimon and The Americans' Stephen Schiff.
Helmed by showrunner, Stephen Schiff, the Cassian Andor series stars Diego Luna, Alan Tudyk, Genevieve O'Reilly, Stellan Skarsgård, Denise Gough and Kyle Soller. The Star Wars series does not have a release date, though is expected to premiere on Disney+ sometime in 2021.
