Deliberate mistake: In the Spanish version, the headlines of the newspapers are in Spanish, but the rest of the articles are in English. It helps supports the narration, but it causes a very weird effect.
Deliberate mistake: In the scene where Helen snags a ride on one of the rail cars (grabs it with her hands then does her Tarzan imitation), one of the support beams for the track magically disappears to give her more space to grab the car. The camera doesn't cut, or even change position- it just pans, all in one shot. When she looks forward at the track, there's one beam a short distance in front of her, and one beyond that. She turns to see a rail car approaching, and when the camera pans back to see her grab the car, the distance to the next support beam has been doubled- the first beam disappeared. (01:16:25)
Chosen answer: If any object can move across the water quickly enough, the weight isn't transferred completely. In some Scandinavian countries, they actually DRIVE very quickly across water in adapted vehicles. If the character of Dash could actually run that fast, it is feasible and possible for him to run on the water's surface.
