4K Noob, question about Hz and FPS with movies.

[Solomon]

So i just bought my first 4K TV and 4K bluray player and i watched a small amount of IT 4K and i noticed that it said it was running at 24HZ? Is this normal for a movie even in 4K? I mean the whole point i thought was that movies would run at 60Hz or whatever so i made sure as best as possible to get good HDMI cables for the TV, Soundbar and 4K UHD player to only see the movie IT running at 24hz. Am i missing something here or is this normal? I know that films at shot in 24 FPS but how does one achieve 2160p60 if that is the case? Any and all answers would be appreciated!!!!
