When Katie drops the book in the hotel, the book lands with the pages open. However, when Latimer picks it up, the book is closed with cover facing up.
Latimer's light plane runs out of fuel and the engine quits, which forces him to glide the plane in for a landing. This being the case, the propeller should have stopped spinning, yet the entire time AFTER he's out of gas and the engine has supposedly quit, you can clearly see the propeller spinning at high RPM, which would indicate an engine still running normally, with ample fuel.
Browne refers to Latimer's 1911 semi-automatic pistol as a revolver. Latimer doesn't correct him.
When the plane is out of fuel, Katie looks to her right and mentions an open clearing, but Mike makes a wide sweeping turn to his left to approach said clearing.
After Latimer killed one of three dogs in close combat . you can see there are still three dogs chasing them to abandoned church .
After the radio has outed Katie as a magazine writer, Widmark sulks in his room. Then he grabs a lamp off the wall to leave his room. But as he holds the lamp, which is between him and the wall, the lamp casts a shadow on that wall. It also casts a shadow on the wall behind him, which means the light is making a 90 degree turn. With the lamp to his left, and between him and the wall, there should only be one shadow cast, and that should be toward the camera.
