Other mistake: The giant medallions that Pilate takes from a chest and then places on the pillar of the Temple do not bear close inspection as images of Tiberius, for some reason the name Augustus is lettered along with abbreviations not easily discerned as what was then used. The image behind Pilate when he is in court is similarly inauthentic but I would think that no-one but an exacting numismatist would even notice this if it is indeed such a major mistake.

Directed by: Nicholas Ray
Starring: Jeffrey Hunter, Hurd Hatfield, Ron Randell, Siobhan McKenna
Continuity mistake: When Jesus is being flogged, he is turned over onto his back, and whipping is heard. Later on, no marks are to be seen.
Trivia: Jeffrey Hunter, the actor playing Jesus, had his chest and armpits shaved for the part (why is anyone's guess). He was also barred from giving interviews.
Question: Why do the Roman soldiers in this film seem to rescue the Innocents from Herod's men?
