Spielberg suggested that Boam write the next draft, and Lucas agreed to it. Boam felt some nervousness going into the process. He joked that "the battlefield was littered with writers before I came on to the scene. There were four or five before me. Each writer had their script next to them covered with blood." Boam said that when Spielberg called to offer him the job, Spielberg said "something like, 'You wanna get real rich?' and I said, 'Yeah, why?' and he said, 'I think you should do the next Indiana Jones movie.'" Boam is reported to have replied to Spielberg's offer by saying, "I just don't know why you didn't come to me before." Boam spent two weeks filled with eight-hour days working with Lucas to develop the story. The two blocked out all other commitments to create the story, building it "beat by beat". Lucas already knew many of the set pieces that were to be in the movie. During the two-week story conference, Boam worked to incorporate it all into the new narrative. "Jeff was very collaborative," Lucas said, adding, "He'd try to include both Steven's ideas and my ideas, and tried to get what we wanted done."
