In a larger town near me (Lima) they are showing Spiderman 3 18 times a day starting at 9:15 in the morning.
Lima's Population: 40,081
Average seating of a theater: 150
Show times per day: 18
If everyone who lived in Lima went it would take the theater 14.844 days to show every man, woman and child in Lima the movie one time.
And at an average of 7.50 per ticket, it would garner the theater $300,607.50
