Madero is shown being shot by Pascal at Madero's desk in his office in the Presidential Palace in Mexico City. In reality, Madero and his Vice President were shot by soldiers of Gen. Victoriano Huerta, who had overthrown Madero and was having him transported to a prison outside Mexico City. The car they were in stopped behind a building outside the prison, and Madero and his vice president were taken outside the cars and shot.
In the original version of this film, during the scene in which Wallace Beery tries to rape Fay Wray and she shoots him in the arm, Beery horsewhips her after she begins laughing hysterically at him. The whipping is shown only by their shadows on the wall. After the Production Code went into effect, this scene was edited, and it is the edited version that was officially available for years. In 2015, the scene was restored, and was reinstated in the Warner Archive Collection DVD.
