Earlier Jesus movies showed him being nailed through the wrists, but revised thinking on this point has prompted recent movies to show Jesus being nailed through the wrists. Perhaps to please both points of view, "The Lamb of God" shows nails being hammered both through the palms AND then through the wrists. Unlike crucifixions in other Jesus movies, this one thankfully dispenses with those ropes which are merely there to help hold the actor's arms in place.
Earlier Jesus movies generally showed him accepting the pain of crucifixion without struggle or even murmur of complaint. In Joseph Breen's made-in-Spain Jesus movie from the late 1950s, for example, it takes 10 blows of the hammer to nail Jesus' left hand, 14 more for his right hand, 6 for his left foot and 7 for his right one. That's 37 agonizing blows from a hammer driving nails through his flesh but this Jesus lies there calmly, not squirming, not even saying "ouch." This approach has changed. It now seems okay to show Jesus reacting to his pain, even letting out a few cries. Jeremy Sisto, the star of the 1999 "Jesus," actually howls in agony and writhes in a most undignified manner as he's crucified. The Jesus in "The Lamb of God," however maintains a serene silence. His feet are not being shown nailed but this omission is not uncommon in Jesus movies.
As to whether Jesus should look frail and aesthetic or healthy and robust, "The Lamb of God" goes with the latter view. In fact, handsome Mark Deakins, who plays Jesus, might even be called a "hunk," though he has no hair on his chest. (Unless it was shaved off.) He does have hairy armpits, however, unlike Jeffrey Hunter in "King of Kings." In this film Jesus has no interplay with the two thieves and there's no scene of him being speared in the side.
