Simon and the villain are wrestling in the mine shaft in the final scene. The villain has a luger, which Simon knocks out of his hand. However, the gun that lands on the ground is an ordinary automatic, which is then used for the rest of the scene.
When Templar goes to Coleman's house he asks for a whiskey and soda, but in the next minute he is holding a snifter of brandy or cognac.
During the scuffle in the mine, when the man falls into the mine shaft the side can be seen moving as if it was made of foam rubber and not solid rock.
