The relative rarity of diverse casts might suggest that they have little money-making potential, but after parsing the data, the researchers came to the conclusion that audiences don’t reject films with diverse lead actors—they actually prefer them. According to Kuppuswamy and Younkin, adding more black actors in principal roles had a beneficial effect on box-office outcomes. The films that had only one black lead actor performed about as well as those films that had none. But films that had two or more black actors playing main roles performed even better, boosting box-office revenues by more than 60 percent compared to films that didn’t have any black lead actors.
