Yeah, but Jim was always about playing around in new media. I mean, that's how he got his start, just wanting to be on TV.
But I do not see him going back and changing everything, replacing sequences, CGI super impositions in older films. I DO see him using newer technology for future projects, just not monkeying around with the old ones, like Lucas is doing here. If Jim was obsessed with future technology, I'd dare to say he'd rather leave the older stuff in the dust than screw with it... but I would like to think he kept some of the classic styles and characters going.
George is all about thinking he wants something that he thought he wanted. He's said stuff like I wanted Mos Eisle to be a bustling space port and I wanted the Puppets in Jabba's palace to perform a musical number. In cases, he says he wants outcomes to be different, awkward connections to anachronistic movies, and all that stuff.
There's director's cut (where the director's version of a movie with scenes cut by the studio so multiple runnings can fit in a multiplex or to get a specific film rating), but this is director's meddling. A few new scenes here and there that pre-existed are fine... but when they have to change the content in the movie, that's ridiculous.
That said, I REALLY hope the awkward musical number based on the Musical version won't be added into The Lion King 3-D. I mean, could they at LEAST have got someone that sounded more like Rowan to do the voice. it's hardly seamless.
