Someone Used a Deep Learning AI To Perfectly Insert Harrison Ford Into "Solo: A Star Wars Story" (gizmodo.com) 130

Andrew Liszewski, writing for io9: Casting anyone other than Harrison Ford in the role of Han Solo just feels like sacrilege, but since Ford is now 76 years old, playing a younger version of himself would be all but impossible. Or at least impossible if you rely on the standard Hollywood de-aging tricks like makeup and CG. Artificial intelligence, it turns out, does a pretty amazing job at putting Ford back into the role of Solo. The YouTube channel "derpfakes" has been posting videos that demonstrate the impressive, and at times frightening, capabilities of image processing using artificial intelligence. Using a process called deep learning, an AI analyzes a large collection of photos of a given person, creating a comprehensive database of them in any almost any position and pose. It then uses that database to intelligently perform an automatic face replacement on a source clip, in this case replacing actor Alden Ehrenreich's face with Harrison Ford's.

    It's far from perfect, and the bitrate on that video is abysmal. If he tried this on Blu-ray footage and kept the quality up, Harrison Ford's face would stick out like a sore... face.

      But if this is a single user effort, imagine what the resources of a movie studio could do with the concept.

        Uh, give us a Disneyfied, PG-13, poorly written, and poorly cast Solo movie? Wasn't that major movie studio the entire problem to begin with?

          I think it is more due to Star Wars fatigue. Star Wars really never was a good set of movies. However it was often people first step into the Epic Sci-Fi action flick. So a few movies every 20 years, isn't the big of a problem, because a new generation will come in and enjoy it. But with one every year, The generation is already sick of it. Because they are not getting an new experience from it.

            A good story well told is always fun. What fucked star wars, idiots who did not understand science what so ever, thinking they were geniuses at everything because that's what their marketing department told everyone, allowing really, really, dumb stories, like bad Saturday afternoon cartoon stories, being told with hundreds of millions of dollars and trying to cover over the mess with PR=B$.

            The animated series Star Wars Clone troopers was better written and had better stories than the movie even Star Wars R

      • They might even do it all the time, but they didn't tell you.

      • Which is why it's super important for actors to copyright their "likeness" and closely guard that IP!
      • We've seen what they can do: they can still only get it almost, but not quite, perfect.

    • To be fair, the data of "young Ford" the algorithm had to work with is decades old. It would be really interesting to see what it could do with data from an actor of the "Blue-ray" era, although in second though the algorithms used to compress the data would actually make things worst. Lossless scans from the high quality film era would probably be ideal but the shear amount of data to be analyzed would make things enormousness computationally expensive
      • By the time an actor from that era is old enough for this to have a point that quality will be even worse, analog scales up where digital really doesn't.

        And mostly on high quality 35mm stock.

        Why would that make any difference. Pretty much all of Ford's old movies are out on Blu-Ray by now. Also 1080p digital has far less detail than high quality 35mm.

        You spelled Blu-ray wrong. Also the data of young Ford from the 1970s/80s is in Ultra High Definition (aka film), so the data is not deficient.

        • You spelled Blu-ray wrong.

          Oh, so you were confused about what they meant? No? (obviously not)

          Then you're just being a dick for the sake of it...

    • It isn't nearly as good as that Hoff guy in Gaurdians' Inferno

      It almost makes me want to paint my car and install some red LEDs with a ring counter!!!

    • ... as much as the atrocious writing in that tire fire of a movie. And their ain't much we can do to fix that, at least not for the foreseeable future.
  • no not perfectly at all
    • It might not be perfect but it is a lot better than what the studio did with Carrie Fisher and Peter Cushing in Rogue One only a couple of years ago.

        Two words, "small screen".

        Honestly, I expect if you blew up that fan-made clip to watch on a 60 foot screen, you'd probably notice it far more than you did watching this video on a comparatively tiny computer monitor.

      I agree. The chin's all wrong.

  • The uncanny valley comes to mind. In some scenes the face droops a bit too much for it to be unrealistic. He's done similar ones on his channel in which the problems are more clear, fitting one face on another is possible but not invisible.

      And there's a least one driving scene where his face is visibly out of proportion to both his body and the face of his girlfriend (who's in the passenger's seat next to him). It looks like he's wearing a Young Harrison Ford Halloween Mask (tm) ...

  • Frankly I preferred the original actor face to the replacement.

    Now what I would have liked, was to tweak the audio so he sounded more like Harrison Ford, with at least a bit deeper voice. This clip was educational in that respect as when watching the movie I was trying to think why he didn't seem much like the original.

  • would be better with blockchain.

    Can they erase Jar-Jar? Or replace Hayden Christensen with an actual wooden post?

  • His previous work of inserting Elon Musk as Bond [youtube.com] is even better.

        We need a Bond movie with both an Elon Musk and Jeff Bezos character. Bezos would be the villain, of course, Musk would just be the red herring. With all the money going into Blue Origin, and they're still not further along than they are? He's definitely hiding some tech for evil purposes! The climax scene would involve Bond in a space suit, crawling into a Dragon v1 capsule so that he can save the day.
  • I think it's not unreasonable to find more de-aging being done (like in Ant-Man and the Tron Sequel). Actors better have good estates that can defend (and license) their likeness because it's going to get easier and easier to replicate them as technology gets better and better. The money involved would be crazy. Imagine if Terantino got Clint to do voice over work for a new Spaghetti western style flick where the actor is being played by a stand in that is manipulated by CG to look like Clint from the 60

      Deepfakes is using only existing footage of the actors and of the movie it is inserted in.
      In your scenario, there would instead be access to a 3D-scan of the original actor's face which could be fixed up and animated based on motion capture dots on the new actor's face. With those, you could produce an even better result.

      ... Which is exactly what was done to Peter Cushing and Carrie Fisher in Rogue One - A Star Wars Story and to Sean Young in Blade Runner 2049 [youtube.com].
      While Peter Cushing is not alive, life-casts

      • Yea, If I were a big movie star I'd have my face detail mapped when I was young (or immediately to retain as much youth as possible) so that in my later years the accuracy would be there. I wonder if some big actors are voluntarily doing that yet?
  • Looks as realistic as Jar-Jar. But it is deep learning AI so it must be good.
  • Now let's go back to Episodes 4,5,6 and remove all the added Lucas crap to the original theatrical releases, and oh yeah, Han shoots first...(yeah I do know about the fan versions and have them.)

    Then back to 1,2,3 and remove Jar Jar, except for killing the character in EP 1

    Then you could make it look like Hayden actually cared about being in a movie, instead of waiting in a line for a new iPhone.

      There are many fan-edits to Star Wars out there, both for restoring the original Star Wars, removing the SE additions, and for making the prequels less cringey. The most famous de-specialisation project has an article on [wikipedia.org] even.

      There are also a few groups that have located surviving prints of the original movies, scanned them in 4K and are performing digital restoration on them. See for instance, Team Negative1's work on [youtube.com].

      For Disney/Lucasfilm to re-release the original trilogy in good quality would be difficul

    • You should search on your favorite P2P tracker for the "Despecialized edition" of the original Star Wars movies.

  • Short people are easy to spot based on the head to torso ratio. While not exactly short, Ehrenreich does not have the same stature as Ford. It makes the fake look really weird to me.
  • Pretty amazing job my ass. Looks absolutely terrible.

    Yeah I know this is a fanboi job and I give *him* credit for this, but boo on Gizlozer for overhyping it.

  • One of the worst aspects of "Solo" was the actor's thin reedy voice v.s. Ford's deep super-masculine voice.
  • Next step;
      Keep Ford, and replace everything else with the footage and story from A New Hope.

  • The article doesn't say anything about the technology, other than to describe it as "deep learning AI." What exactly does this mean? Is it a neural network? If it's not, it's not really "AI." Deep learning? Maybe, or maybe it's just brute force that runs on really powerful equipment. Can't tell from the article.

  • It looks like someone wearing a Harrison Ford mask. It shows, very clearly, just how good Harrison Ford is as an actor.

    This is certainly his face, but it isn't his facial expressions. It isn't his smile. It isn't his brow furl. Those aren't the way that his eyes widen.

    Simply put, it doesn't move correctly.

    And that means that the mechanisms by which Harrison Ford's face is attached to his head are betrayed. Dimples might be there, but they don't restrict the skin's movement.

    It's awesome, in terms of tec
