You might think that charging $25 for Iron Man and $7 for Lincoln would make the most money, but it might actually be the other way around. Or they market might actually do better with all movies being $5.
I suspect the industry will follow the market. The best way to make the most will be what they charge. It’s a very elastic market. Lots of alternatives for the entertainment dollar.
They put they wrong price on a movie and they might just find themselves making zilch.
I remember in the 1980s when $1 theater second run houses ran wild. People would go to the movies at the dollar multiplex and often watch just about anything that was screened.
Eventually the theaters became run down.
