During an appearance on Jimmy Kimmel Live for The Lion King, director Jon Favreau revealed that he is already working on the script for Season 2 of The Mandalorian TV series.
Following Kimmel’s question of, “Can ya tell us anything about The Mandalorian or is it secret?” Favreau responded, “well it’s secret, but I’ll tell ya.”
“It’s about a bounty hunter, it’s after Return of the Jedi. So the Empire’s gone and all hell’s breaking loose in the outer rim and its about the scum and villainy, that now once you take out the rule of law – what happens?” Favreau continued, “Chaos takes over and you have a lot of the unseemly characters. It’s kinda like, ya know, when you meet Han Solo at the beginning of Star Wars: A New Hope.”
