How much extra does it cost to show an extra movie that nobody shows up to? It seems like the majority of the cost is rent of the building and salary. If employees are already working to operate the few movies that are expected to have people and the building is already being paid for then they may as well use up all their theaters just in case since the extra cost would be low.

Especially since you may have someone walk-up and willing to buy-in to the movie even though it started ten minutes ago, so I think I've answered my question above - they just show everything no matter what the sales look like.
