Jon Favreau Was Scared The Mandalorian’s Season Finale Cameo Would Be Spoiled

Warning: Spoilers follow for the season two finale of The Mandalorian.

Jon Favreau is amazed that the big surprise cameo in The Mandalorian’s season two finale was kept a secret, and discussed the scene in a new interview. Favreau appeared on Good Morning America on Monday and talked about Luke Skywalker’s appearance in the episode to be a deus ex machina, fighting his way through an army of Dark Troopers and eventually taking Grogu with him (with Din Djarin’s consent). You can check out a couple of highlights below, per TV Line:

On the cameo staying secret: “It was very tricky, because it’s very hard to keep a secret nowadays. There are so many people involved with the process. Every piece of [Season 2] casting leaked, so we were so scared, right up until it aired, that our surprise cameo was going to leak, too.”

On Mark Hamill being present for the scene: “And then to have the very last episode, to have Mark Hamill actually on set filming and us using whatever technology we had available to de-age him and try to make him look as much like he did in the old films [was special].”
