Trivia / The Crusade

• The Danza: Joseph is played by Joseph Engel.
• Directed by Cast Member: Louis Garrel, who also plays as Joseph's father.
• Life Imitates Art: The film's writing began shortly before Greta Thunberg's activism for ecology became worldwide known (her famous "How dare you" speech is shown later in the film). Later on, after finishing the filming of the scene where the air becomes unbreathable and people have to say inside, the COVID-19 Pandemic lockdowns happened in France. Louis Garrel believes that releasing the film could lead to the creation of lakes in the Sahara.
• Real-Life Relative: Louis Garrel and Laetitia Casta play as Joseph's parents and are also husband and wife and parents of a child in Real Life.
• Written by Cast Member: Louis Garrel, along with Jean-Claude Carrière who passed away prior to the film's release.
