Spielberg described the draft as good but too long; Kasdan and Lucas collaborated to trim and refine it. The script was a globe-spanning tale set in the United States, Egypt, Greece, Nepal, and Shanghai. Several elements were cut, including a journey to Shanghai that would lead to a minecart chase and Jones using a gong to shield himself from gunfire; both ideas were re-used in the film's sequel "Indiana Jones and the Temple of Doom" (1984). To his frustration, much of Kasdan's love story between Jones and Marion was trimmed, as were scenes showing the mutual attraction between Marion and Belloq. The screenplay was completed by December 1979.
