A database called ShotOnWhat.com provides detailed technical specifications for feature films including acquisition format, cameras, lenses, and distribution resolution.
The difference between 2K cinema standard and 1080p distribution is relatively minor in practical terms.
When viewed at 1.5 times the screen width distance, human visual perception can typically discern approximately 720p resolution equivalent or around one million pixels.

The ShotOnWhat.com database may lack specific details such as camera model and original acquisition resolution for some films.
The observation about human perception limits at 1.5x screen width viewing distance is unsourced and not independently verified in this discussion.
The discussion centers on theoretical resolution comparisons rather than practical quality assessments of final delivered films.
