At the end of the film, the President, speaking of the sacrifice by Chris and Linda Cronyn, says "the whole earth is their sepulcher". That phrase appears in the Garden of the Missing at the American Cemetery at Colleville-sur-mer above Omaha Beach in Normandy. In the cemetery the full phrase is "Here are recorded the names of Americans who gave their lives in the service of their country and who sleep in unknown graves. This is their memorial. The whole earth is their sepulcher, comrades in arms whose resting place is known only to God."
