Continuity mistake: Go to the scene where the crowd is going to Golgaltha, along with the soldiers and Jesus. After they have taken off Jesus' clothes, and have tied him to the cross, they show a close-up of one of Jesus' hands, with a nail on-top, held by a soldier. Look closely - it's his left hand. Then the camera zooms out, and you can see the whole body of Jesus, and the soldier drives the nail into his right hand. Look at his left, and no nail is in it.
Factual error: In 1947, when George is 14 years old his father takes him to the clinic for a physical examination. This is about 18 minutes into the movie. The nurse measures his blood pressure using a cuff that is held on with a "Velcro" hook-and-loop fastener. Velcro wasn't marketed until the early 1960's. [A new DVD was released in 2014. The sound track in this scene was edited and we can no longer hear the sound of the Velcro being unwrapped.]
