The Chinese anti-war film "Once Upon a Time in the Middle East" is now playing in theaters across China. Since its nationwide release on August 11, the film has won strong reviews from both critics and audiences for offering new cinematic narrative on war and peace. Sixteen-year-old Egyptian actor Omar Sherif, who plays the teenage orphan Saif in the movie, and Mohamed Osama, the producer responsible for casting Arab talent for the film, recently sat down with CGTN's Lyne Lin to share some behind-the-scenes stories from the production.
