On a physiological level, the film looks to be factually incorrect. It shows the soldiers driving a nail into the palm of Jesus' hand. In contrast, the image on the Shroud of Turin shows nail wounds in the wrists, not in the palms of the hand. Scientists who have examined the Shroud have used this seemingly minor detail as evidence of the Shroud's authenticity -- in order to support the weight of an adult human body, a nail must be driven through the wrist between the radius and ulna bones, mot through the palm.
This caused me to wonder about, then, Thomas' insistence on seeing the "palms" of Jesus' hands, but an expert on that era at Miami University, Ed Yamauchi, informed me that the Greek word for "wrists" and "palms" was the same. So Thomas said he wouldn't believe until he put his fingers in the holes in the wrists.
