Input: Question: How many total films did Sedat Simavi work on? Passage:Cinema of Turkey, also known as Yeşilçam (literally means The Green Pine in Turkish language) (), is the sobriquet that refers to the Turkish film art and industry. It is an important part of Turkish culture, and has flourished over the years, delivering entertainment to audiences in Turkey, expatriates across Europe, and more recently prospering in the Arab world and in rare cases, the United States. The first film exhibited in the Ottoman Empire was the Lumière Brothers' 1895 film, L'Arrivée d'un train en gare de La Ciotat, which was shown in Istanbul in 1896. The first Turkish-made film was a documentary entitled Ayastefanos'taki Rus Abidesinin Yıkılışı (Demolition of the Russian Monument at San Stefano), directed by Fuat Uzkınay and completed in 1914. The first narrative film, Sedat Simavi's The Spy, was released in 1917. Turkey's first sound film was shown in 1931.
