Which 1978 film, directed by Mohamed Khan, launched the Egyptian 'neo-realist' movement by shooting entirely on the streets of Cairo with a handheld camera and non-professional actors?

• A Awdat al-Ibn al-Dal (Return of the Prodigal Son)
• B Darbet Shams (Sunstroke) ✓
• C Al-Darb al-Ahmar (The Red Alley)
• D Al-Raghba (Desire)

Mohamed Khan's 'Darbet Shams' (1978) abandoned the studio-bound polish of classic Egyptian cinema, using location shooting, available light, and documentary-style camerawork to depict working-class Cairene life — it inaugurated a realist aesthetic that shaped the 1980s generation of filmmakers.
