EW has this latest bit of news (sort of) with their "highly placed source" saying, “Harrison is open to the idea of doing the movie and he’s upbeat about it, all three of them are.” As fans already know and have deconstructed, it was revealed that George Lucas met with Mark Hamill and Carrie Fisher prior to the official announcement of Lucasfilm's sale and the new trilogy of movies. But the news of Ford being interested is somewhat surprising.
As Movieline nicely noted a couple of years ago, Ford has a long history of being generally disinterested in talking about, acknowledging or referencing the franchise that made him a star. And his last outing for Lucas in "Indiana Jones And The Kingdom Of The Crystal Skull" wasn't exactly a shining moment for everyone involved. But maybe since Lucas won't be directly involved (he won't even choose the director), maybe that's an incentive. And Ford's last few movies -- "Extraordinary Measures," "Morning Glory," "Cowboys & Aliens" -- haven't been so hot either.
But that said, Ford isn't moving until he sees a script and who knows who the director will be. So basically, the spin that he's "upbeat" might just be relative to the fact that he hasn't turned them down yet. Who knows how he'll feel next week, next month or next month. And does he really want to start getting asked all over again about Han Solo and the saga, which the 70 year old actor so clearly disdains it? Maybe if he gets it in his contract he doesn't have to press, that'll be another push in the right direction. Or, maybe by then Ridley Scott will need him for "Blade Runner 2."
So in short: we'll see.
