Watch on 123Movies. The 21st-Century Cinema Index, an extensive research project on 21st-century film by Hasan Cem Çal, a writer whose work focuses on the evolution of the moving image, has been adapted into a video essay by Hazal Bayar, an academic known for her experimental short films. Written originally for Manifold, one of Turkey’s leading online platforms, the work serves as a unique gallery of foundational images and concepts of the past twenty-five years of cinema.
