Problem: Steven Spielberg:

Next, Spielberg teamed with Star Wars creator and friend George Lucas on an action adventure film, Raiders of the Lost Ark, the first of the Indiana Jones films. The archaeologist and adventurer hero Indiana Jones was played by Harrison Ford (whom Lucas had previously cast in his Star Wars films as Han Solo). The film was considered an homage to the cliffhanger serials of the Golden Age of Hollywood. It became the biggest film at the box office in 1981, and the recipient of numerous Oscar nominations including Best Director (Spielberg's second nomination) and Best Picture (the second Spielberg film to be nominated for Best Picture). Raiders is still considered a landmark example of the action-adventure genre. The film also led to Ford's casting in Ridley Scott's Blade Runner.

Context and question: Following the earthquake, Joseph I gave his Prime Minister even more power, and Sebastiao de Melo became a powerful, progressive dictator. As his power grew, his enemies increased in number, and bitter disputes with the high nobility became frequent. In 1758 Joseph I was wounded in an attempted assassination. The Tavora family and the Duke of Aveiro were implicated and executed after a quick trial. The Jesuits were expelled from the country and their assets confiscated by the crown.
