What is one of the key revenue metrics for movie studios?

The key revenue metric for movie studios is primarily related to their ability to produce and distribute films effectively, and the utilization rate reflects how efficiently the studio is using its resources, such as talent, budget, and equipment, to generate revenue from film productions. A high utilization rate indicates that the studio is effectively capitalizing on its assets and resources, which is crucial in the highly competitive film industry where maximizing returns on productions is essential.

In contrast, the other options address metrics that are less directly related to the revenue generation mechanism for movie studios. Annual profit margin does provide insight into a studio's profitability after expenses, but it doesn't capture the operational efficiency aspects that utilization rate does. Employee turnover rate is significant for understanding workforce stability and personnel management but does not directly influence revenue generation. Client acquisition cost, while important in marketing and sales contexts, is less applicable to studios since the focus is more on the distribution and audience reception of their films rather than acquiring clients in the traditional sense.
