This is a bit off topic, so please feel free to let me know if I should put it under a different thread, but John Patrick has a list of Biblical allusions in literature and what used to be common speech (which could translate to movies) here. Meaning, Metaphor and Allusion - Dr. John Patrick
Many are out of use now, and we would never recognize them. However, one that struck me was “And if not…”. It was used by the British troops who were encircled by Germans in Dunkirk as a message back home. This was the quote from the Hebrew young men when the king was going to throw them into the blazing furnace for not worsihiping his idol–“If it be so, our God whom we serve is able to deliver us from the furnace of blazing fire; and He will deliver us out of your hand, O king. But if not, let it be known to you, O king, that we are not going to serve your gods or worship the golden image that you have set up” (Daniel 3:17-18). "But if not..."
The British public knew what it meant, and apparently many civilian boatmen volunteered to help them across the Channel, along with others…
I’m not sure if that story got into the move, “Dunkirk,” though. …and that was OT, not Christ, imagery. Sorry!
