Cameron also said he doesn't really like the HFR on traditional dialogue scenes, but rather for the rest, and I kind of agree. Well, I wouldn't trade 24 fps for anything else, except on select films, but watching Dr Strange the other day, I kept thinking during some of the action scenes "jesus f***, you can't see anything really, plus it's cut really fast", then again, using HFR on action that's not like totally CG is going to be a dead giveaway for stunt doubles as well, some said also with the 4K 120 fps 3D in Billy Lynn, you not only notice the acting more (which is what Ang said, actors have to be more natural because you see everything) but also that the extras in the background are terrible.
Now, about the action, if you have long takes, single shots, that's the way to go, but for the other stuff, it could benefit from a higher framerate, but you'll lose that movie magic. It seems also from a thread on Film-tech that Sony is pulling back from a wide HFR release, some people in the know said there will only be in the US the 4K 120 fps 3D (as planned), the Dolby Cinema versions, and the rest will be 24 fps 2D for the rest, apparently, some were showing the technical tests they received to make sure they could display the film properly and there were some worrying pics of tests failing. Apparently, there will be more HFR shows overseas (hope so), but it would seem Sony is getting cold feet, or perhaps would rather avoid a media fiasco with unproperly projected HFR shows. I remember The Hateful Eight's messy 70mm roll-out, I saw an impeccable 70mm print, but many did not.
Me think Sony would rather have limited HFR showings in Dolby Cinema theaters and the limited 4K 120 fps 3D ones, something they can have some control over, terrible HFR shows could be very harmful. The Academy is also going to see the movie in 2D 24 fps, which is a smart move.
