The film will be screened in the section "Treasures - Revived and Restored from the World's Archives".
The Dupes is based on Palestinian novelist Ghassan Kanafani’s classic novella Men in the Sun.
The novella depicts the tragedy of a group of Palestinian refugees who travel hiding in the back of a truck amid sweltering desert heat to find employment - and a new life - in an Arab Gulf country.
The film won Tanit d'Or at Carthage Film Festival in 1972.
"This uncompromising film was banned for decades. It still has the power to unsettle audiences in this striking restoration," reads the London festival's brochure.
The restored The Dupes has been screened in the UK and Egypt and in various international festivals and cinematic events.
The Treasures segment will also present The Black Pirate (1926, USA), Macario (1960, Spain), Peeping Tom (1960, UK), Pressure (1975, UK), and The Stranger and the Fog (1974, Iran).
The festival will also screen films within its competitive segments - Official Competition, First Feature Competition, Documentary Competition, Short Film Competition - and other films on the sidelines.
Another Egyptian film, The Goose's Excuse (Ozr El-Wezzah), which is directed by Mahdy Abo Bahat and Abdo Zin Eldin, will take part in the festival's short film competition.
