The Last Duel is based on the Eric Jager book Last Duel: A True Story of Trial by Combat in Medieval France. The film takes place in 14th century France and centers on best friends Jean de Carrouges (Damon) and Jacques Le Gris (Driver), who are ordered to fight to the death after Carrouges accuses Le Gris of raping his wife, Marguerite de Carrouges (Comer).
Production on The Last Duel was halted in March due to the COVID-19 pandemic and resumed in September in Ireland.
Damon and Affleck previously co-starred in School Ties, Good Will Hunting, Dogma and Jay and Silent Bob Strike Back, while Damon and Scott collaborated on the 2015 film The Martian.
