Yordan recalled, "I didn't want to go to Spain, but he asked me to just come over there for the weekend. The picture was called "Son of Man". Terrible title, and someone had taken chapters of the Bible and sort of tried to make it play." He then recommended re-titling the script to "King of Kings". Yordan wrote a new script in six weeks which Bronston liked so much that he encouraged him to stay in Madrid, in which Yordan later went to co-write the script for "El Cid" (1961). Throughout the writing process, Yordan felt he did not find writing the movie to be difficult, in which he argued that "Christ was a loner. He's not much different than my usual character. The Western character. It's the same character. The man alone."
