Some of these pictures and descriptions may give away plot details that you might not want to know before watching the film.
While driving cattle in Oklahoma, in a very elegant movement, Montgomery Clift leans far over the side of his horse while still riding forward and reaches into a small bush. The camera cuts back to show him holding a Texas horned lizard in his hand. The effect looks so spontaneous that I sometimes wonder if it was in the original script or if it was added on the set. If it was in the script - then I'm not sure what are they trying to tell us about Clift in the scene other than he has great eyes to spot a horned toad in the brush from a distance while riding a horse and the flexibility to grab it from horseback.
