We’ve seen a lot of Mark Hamill around the past few days, thanks to Kingsman, but most of what he’s said about The Force Awakens are takes on things we’ve already heard. However, for Extra, he had a few things to say about the Millennium Falcon: “I can’t describe the feeling… the déjà vu of walking onto the Millennium Falcon, remembering all these details that they’ve gotten exactly right… It still seems surreal to me and hard to believe it’s actually happening.”
Note it’s not a confirmation he actually filmed something on the set.
