Same guy, but pre-Schindler. Perhaps he's somewhat older, wiser - and maybe even a little ready to atone for not having done what he could have so many years ago. Then again, he did go that route with Kubrick and "AI" only to come away smarting from the outcome; so the idea, coming at it from the Spielberg side, could be dead in the water.
On the Cruise side, though, he's constantly looking to "deepen" his legacy (although, there, too, his Kubrick experience in a comparable bid was, uh, something short of an unalloyed success).
Guess that leaves us with the Martians. After all, they're finding themselves in the news these days and, true to our times, are probably looking to hire a PR agency to help them work their image. Maybe a bunch of them could offer to be photographed as the last of the Samurai-Martians riding into battle on Spielberg's "Rosebud" sled along the newly-discovered ice of one of their polar caps. On eBay alone, that oughta bring the prop's value back to break-even for SS while giving the TC franchise a whole new extraterrestrial target demographic to exploit.
But isn't it just like the Welles boys, H.G. and Orson, to have foretold the truth all along: in the end, man's best friend is his Martian?
