In Quentin Tarantino's original script, Clarence was supposed to die in the final shootout. When Tony Scott made this film, he had already decided to change the ending. Quentin Tarantino begged and pleaded with him to keep the original ending. Scott agreed to film both endings but would decide which ending to put in during editing. Of course, Scott decided to go with his ending where Clarence lives.

After viewing the film Quentin agreed that for Tony Scott's version the ending was the right one for "Scott's film". Quentin stated if he made the film, the structure would have been different, and in the end Clarence would still have died.

Vincent was interrogating Clifford (Clarence's dad) about the whereabouts of Clarence and Alabama. Vincent had basically told Clifford that he couldn't save his son, but he could save himself by giving up Clarence's whereabouts. Obviously Clifford would never give up his son to be killed, however Vincent and his men were torturing him for information and were too good at detecting when he was lying. So Clifford smirks, ponders for a moment; Then proceeds to mock Vincent's Sicilian ancestry, seeing as how men of his stature take these things very seriously. Knowing how deeply offended Vincent would be by this, Clifford was counting on Vincent being provoked into killing him. Therefore Clifford would receive a quick death and leave his son's whereabouts a mystery, instead of being tortured into confessing.
