Well, despite an earlier report that Harrison Ford had officially joined Star Wars, to at last fulfill our child dreams of seeing a septuagenerian Han Solo truly confused when he asks who's scruffy looking, it seems none of the old cast is actually signed on. Mark Hamill has cleared up that rumor with EntertainmentTonight, telling them, "I can tell you right away that we haven't signed any contracts." But, hey, don't worry: He also provided us some new wild speculation!
Like, have you wondered where Luke Skywalker would be in Episode VII? So has Mark Hamill! And though he says he has no actual information on the subject, he's more than willing to toss out some conjecture on what a lonely, depressing, forever-alone sad-sack his character probably is. Said Hamill:
"I'm assuming, because I haven't talked to the writers, that these movies would be about our offspring -- like my character would be sort of in the Obi-Wan range [as] an influential character. ... When I found out [while making the original trilogy] that ultimate good news/bad news joke - the good news is there's a real attractive, hot girl in the universe; the bad news is she's your sister - I thought, 'Well, I'm going to wind up like Sir Alec [Guinness]. I'm going to be a lonely old hermit living out in some kind of desert igloo with a couple of robots.'"
Hamill also added that he thinks the entire old cast should return (Billy Dee Williams, too), and feels the new films should hew closer to the original trilogy, which, yeah. But again, none of that is really an official stance, and he has yet to formally meet with anyone involved. We'll just have to wait for more official word on if Luke's true destiny was not in the Dark Side but in the Lipton Pasta Side he eats over the sink every night.
