In general, movie theaters make most of their money from concessions, such as food and drinks, and not from ticket sales. As a result, they have an incentive to keep ticket prices low in order to attract more customers. However, the cost of operating a movie theater can vary, so some theaters may need to charge higher ticket prices in order to stay afloat.
It's worth noting that the relationship between movie studios and theaters is constantly evolving, and the exact terms of their agreements may vary from case to case.
