Goofs

At the beginning of the movie, when the bus is shown en route to the train station, the hubs of the wheels are dirty silver but in the next shot, when the buss is pulling in to the train station, the hubs are black. Not only that but it is not the same train station in the second shot as in the first shot. See more
