You know what we haven’t talked about nearly enough? Luke Skywalker in. It’s the mystery that will not die until December 18. Luke is missing from all thepromotional material. The only thing we know is that it was done on purpose. There’s a reason we don’t see him. Now you could chalk all that up to J.J. Abrams and Disney just trying to build hype. It could be that the secret isn’t actually as big as all that. However, Mark Hamill has now weighed in on the situation himself, and while he was careful not to give anything away, he’s made it clear that the secret is real, and it’s big.Mark Hamill says that his NDA regarding the newfilm actually contains a clause regarding the big secret, whatever it is. He’s actually got money riding on the situation. If the secret leaks, Hamill loses out on some amount of money. He says he had a similar deal on. If he keeps the secret until the day the movie releases, he gets paid. While the amount was not disclosed, this is Hollywood. It’s almost certainly a serious amount of money.Hamill compares the situation to the classic Darth Vader reveal from The Empire Strikes Back . Only George Lucas, director Irvin Kirshner, and Hamill knew the truth about who Darth Vader truly was. The line spoken on set by David Prowse was that Obi-Wan Kenobi had killed Luke’s father. Hamill is obviously proud of his success at keeping the secret. He says he didn’t tell anybody, including his own wife. He tells PC Gamer that he’s not even supposed to confirm that he’s in. We assume since his name is on the poster that the cat is out of the bag on that one. Check out more of the interview below. Important stuff starts at the 11:27 mark.There’s the slightest of possibilities that Mark Hamill is speaking of an entirely separate secret. He doesn’t specifically state the secret is in regards to his own character, though it is implied. The fact is that we don’t even know what it is we don’t know. That’s how deep this rabbit hole goes.So it looks like the Luke Skywalker mystery is real. Is he evil ? Is he not? Is the secret something entirely different? Did he get married and have kids in the last 30 years? We accept all theories, no matter how crazy. Let us know what you think below.
