From EW:
Liam Neeson is returning to that Galaxy Far, Far Away. EW has learned exclusively that the actor will reprise his Star Wars: Episode I — The Phantom Menace role as doomed Jedi Master Qui-Gon Jinn on Cartoon Network’s Star Wars: The Clone Wars on Jan. 28 and again on Feb. 11.
I saw that. That's pretty awesome that he was willing to go back to that character.
