In 2000, Spielberg's son asked when the next "Indiana Jones" film would be released, which made him interested in reviving the project. The same year, Ford, Lucas, Spielberg, Frank Marshall and Kathleen Kennedy met during the American Film Institute's tribute to Ford, and decided they wanted to enjoy the experience of making an "Indiana Jones" film again. Spielberg also found returning to the series a respite from his many dark films during this period, such as "A.I. Artificial Intelligence", "Minority Report", and "Munich".

The four Indiana Jones film scripts were novelized and published in the time-frame of the films' initial releases. "Raiders of the Lost Ark" was novelized by Campbell Black based on the script by Lawrence Kasdan that was based on the story by George Lucas and Philip Kaufman and published in April 1981 by Ballantine Books; "Indiana Jones and the Temple of Doom" was novelized by James Kahn and based on the script by Willard Huyck & Gloria
