Corrected entry: During the scene when Loveless is talking about taking over the U.S. and he mentions some states and Arizona is one of them. Arizona was not a state when Grant was president. (He may have mentioned others that weren't states yet, but this is the only one I remember completely.)
Corrected entry: After Artemis gets rid of Loveless' lady henchmen, the Pres. tells him to come over and drive. While trying, he pulls the middle lever, and the sound of the fireball and explosion is heard. Earlier, when Loveless was destroying the town, he pulled one of the levers to the side to launch the fireball.
Corrected entry: When Jim West and Artemis Gordon are riding away from the train, you can see that Jim is a doll. He's too stiff when he's riding to be a real person.
