Great question — answering as the UphillTech team:
I see nothing relating to this on either Wikipedia or IMDB. You'd think if they were trying some new format, they'd want to tell people about it. BTW, 24fps is traditional cinema; TV is 25 PAL/SECAM [Europe] or 29.97 NTSC [America/Japan]. Artificially interpolating to 60 fps [called Sport mode on some TVs] can make regular cinematic imagery look awful. The eye/brain expects motion blur on cinematic productions, so much so that if it's artificially reduced it looks odd. The brain expects this so much that sometimes it's actally artificially increased, to make action look 'even more cinematic than cinema'. This was one of the things they had to learn in CGI too, to make things look more...
