It really depends on where you measure it. A 4k BluRay is somewhere around 60-80GB for a single movie. But then when that is uncompressed and sent to the actual screens you are talking multiple gigabits a second. With 4k60 being somewhere in the 12 to 18 gbit range at the peaks. If it were at 16gbit for 2 hours, that would be ~14TB of information transferred.
If you are talking streaming bandwidth, Netflix says 25mbit is required for 4k video streaming. If it were to use all of that for 2 hours that is 22GB for a movie. Though its likely only using half that. I haven't actually measured it. And then there is the same inflation to what is sent to screen.
