Indiana Jones and the Last Crusade is a 1989 American fantasy-adventure film directed by Steven Spielberg, from a story co-written by executive producer George Lucas. It is the third installment in the Indiana Jones franchise. Harrison Ford reprises the title role and Sean Connery plays Indiana's father, Henry Jones, Sr. Other cast members such as Alison Doody, Denholm Elliott, Julian Glover, River Phoenix, and John Rhys-Davies also have featured roles. In the film, set largely in 1938, Indiana searches for his father, a Holy Grail scholar, who has been kidnapped by Nazis. After the mixed reaction to Indiana Jones and the Temple of Doom, Spielberg chose to compensate with a film lighter in tone. During the five years between Temple of Doom and Last Crusade, he and executive producer Lucas reviewed several scripts before accepting Jeffrey Boam's. Filming locations included Spain, Italy, England, Turkey and Jordan. The film was released in North America on May 24, 1989 to mostly positive reviews. It was a financial success, earning $474,171,806 at the worldwide box office totals. It won an Academy Award for Best Sound Editing.

Indiana Jones and the Temple of Doom is a 1984 American fantasy-adventure film directed by Steven Spielberg. It is the second installment in the Indiana Jones franchise and a prequel to 1981 film Raiders of the Lost Ark. After arriving in India, Indiana Jones is asked by a desperate village to find a mystical stone. He agrees, stumbling upon a Kali-worshiping Thuggee cult practicing child slavery, black magic, and ritual human sacrifice. Producer and co-writer George Lucas decided to make the film a prequel as he did not want the Nazis to be the villains again. After three rejected plot devices, Lucas wrote a film treatment that resembled the film's final storyline. Lawrence Kasdan, Lucas's collaborator on Raiders of the Lost Ark, turned down the offer to write the script, and Willard Huyck and Gloria Katz were hired as his replacement, with the resultant screenplay partly based upon the 1939 film Gunga Din. The film was released to financial success but mixed reviews, which criticized its violence, later contributing to the creation of the PG-13 rating. However, critical opinion has improved since 1984, citing the film's intensity and imagination. Some of the film's cast and crew, including Spielberg, retrospectively view the film in an unfavorable light. The film has also been the subject of controversy due to its portrayal of India and Hinduism.
