a first-run theater has ABSOLUTELY NO EFFECT on a discount theater.
Interesting thought. If that's the case, then my county (drawing area of over 300,000) now has no discount house. Over the past year, we've lost a single-screener and just last week, a twin. Our first-run houses, many of them suffering the '2-week and it's dead syndrome', still have to hang onto prints just to keep the screens lit. Considering release frequencies, a picture is so totally tapped out by the time it leaves, there's no market for the discounter... either that, or the cheaper ticket isn't suitable motivation in my area.
Currently, there in only one theatre that does not run mainstream product on the break. It's a single screener, located in a high-income, relatively isolated section of our county. It plays the art/independent fare, and appears to reasonably serve what limited audience there is around here for such entertainment.
