Saudi Arabia opened its first movie theater last week, ending a nearly 40-year ban on showing films in public. The global blockbuster "Black Panther" sold out in about a minute.Welcoming Saudi crowds back to the movies is part of Crown Prince Mohammed bin Salman’s plan to reform the ultraconservative kingdom and create revenue sources outside of oil.And in a country where there aren’t a lot of things for young people to do, bin Salman sees a huge potential upside to film. One government body calculated that in 2017 alone, Saudis spent $30 billion on entertainment in the Middle East — all of it outside the kingdom. That’s about 5 percent of the country’s gross domestic product.The plan is to funnel that kind of money back into the country. Over the next 10 years, the kingdom plans to invest $64 billion in the entertainment industry and open up 300 movie theaters across the country.VICE News caught a preview with Fahad al-Yahya, a psychiatrist and film critic in Riyadh who’s been waiting for this day for decades.
