Back of the envelope calculations

5120x2700 = 13.8 Mpixels per frame

assuming 12-bit RGB, 36 bits per pixel, round up to 5 bytes per pixel

yields approx 70 MB per frame

24 frames per second yields approx 1.7 GB/second

3600 seconds per hour yields approx 6 TB per hour

two hour film: 12 TB

Hmmm, I'm off by a factor of 4 somewhere. But yes, uncompressed video is huge. Distribution to theaters is in compressed format.
