A novelization of "Raiders of the Lost Ark" was written by Campbell Black and published by Ballantine Books in April 1981. It was followed by "Indiana Jones and the Temple of Doom", written by James Kahn and published by Ballantine in May 1984. Finally, "Indiana Jones and the Last Crusade" was published in May 1989, and was the first Indiana Jones book by Rob MacGregor. A fan of the first two films, MacGregor admitted that writing the novelization made him "somewhat disappointed" with the third film, as he had expanded the script whereas Steven Spielberg had cut scenes to tighten the story.
