As Episode III bridges the prequel era with that of the original trilogy, many of the characters and situations will begin to resemble or tie in with those found in Episodes IV, V, and VI. A character that played a relatively small but important part in Return of the Jedi will return in a younger incarnation as actor Genevieve O'Reilly plays Mon Mothma in the next Star Wars movie.
O'Reilly has performed such stage roles as Ruth in Cosi, Veronica in The Ugly Man and Olivia in Twelfth Night. On television, she has appeared on "Beastmaster," "Life" and "All Saints." Her film credits include Avatar, and most recently, she played Officer Wirtz in The Matrix: Reloaded.
In Episode VI, Mon Mothma, played by Caroline Blakiston, appears during the Rebel Alliance briefing prior to the attack on the second Death Star. She is the leader of the Rebellion, and expanded universe publications explain that Mon Mothma was once an idealistic young Senator during the fall of the Republic -- the era in which Episode III is set.
