About midpoint: When Mason checks Uncle Harvey's dead body, he sees a purse and a few bills with the end side sticking out. In the next closeup shot, six bills are clearly shown with the long side out. Back to the shot of Mason, the bills are again with the end side sticking out.
Harvey Scott crumples a piece of paper and throws it on the floor, missing the wastebasket, which is near the wall several inches from the edge of the carpet. The scene slowly dissolves to show several pieces of crumpled paper on the floor, but now the wastebasket is several inches from the wall and right next to the carpet.
When Elayna Scott (Barbara Bain) is on the stand, she admits tearing up the message her brother-in-law had left at the hotel. She then says Pamela Blair (Lisa Gaye) was with her and knows why, because she had told Pamela the reason. Then Pamela gets on the stand and testifies to all the reasons Elayna had given for what she did. But that is all hearsay. Best evidence dictates Elayna herself testify to what she said. Removing her from the stand and using Pamela in that manner would never have been done.
When Laurence Barlow is on the stand with Burger, the film was printed backwards, as his hair is combed the opposite direction. When Mason later cross examines him his hair is back to normal.
After Pamela Blair faints, she is still holding her left arm upright.
When Paul Drake is leaving the Scott Ranch after being threatened by a worker, he pulls his car door closed, and one of the large set lights is sharply reflected in the vent window.
When the man on the horse threatens Paul Drake, he levers the rifle, that action would have chambered a round and chocked the hammer back. When Paul leaves, he flips the rifle around and replaces it in to the saddle holster. No one would treat a chocked rifle like that. He should have lowered the hammer. Before flipping the rifle around.
