Indiana Jones and The Last Crusade is riddled with mistakes. At the beginning of the film, Indiana Jones crosses the Atlantic by airliner even though it is 1938-- one year before the first transatlantic passenger service began. In the airport lounge, two people are reading German newspapers that are dated 1918, (20 years before the year in which the film is set. ) Finally, the “Republic” of Hatay is ruled by someone referred to as “Your Royal Highness”.
