Looking at my local theater I think they’ve already adjusted accordingly… Minecraft has 26 showings tomorrow, a working man has 7, Snow White has 5, the Last Supper part 1 has 4, the Last Supper part 2 has 4, there’s 7 movies I’m not familiar with that all have less than 5 showings, and Cap4 has 1 showing. This is at a 16 theater multiplex.
ETA… looking at showtimes I think Minecraft must have 7 or 8 screens, with the other 11 movies sharing the other 8 or 9, Minecraft has XD and Real3d starting every hour, they’d need 3 or 4 screens to pull that off, then they have regular showings starting approximately every 40 minutes, they’d need 4 regular screens to pull that off.
