The US-version misses a scene in the observatory: Dr. Kelston explains that it was theoretically possible for space ships to land on earth if they used other planets as some sort of "springboard". Furthermore, he explains that by the US Army's missile tests, the Mars-inhabitants have possibly been "startled". As proof, he shows David and Dr. Blake newspaper clippings of UFO-sightings and shows some models of UFOs. David identifies one of those models as the saucer he saw. Then the telephone rings. Through the call, Dr. Kelston finds out that the General didn't get in touch for three days now. The US-version continues after the call, when the three sit at the desk again.

After the spaceship's explosion, the German version features a picture of outer space and finally "THE END".

The US-version features David waking up from a dream, running to the window and seeing a thunderstorm. Then he runs to his parents' bedroom. The following dialogue takes place:

David: Mom! Dad! Are you all right?
Mom: Of course we`re all right.
Dad: What`s the matter son? That lightning scare ya?
David: No, it wasn`t that, did you go to the hospital?
Mom: Oh no, we`ve been sleeping. There's nothing to be afraid of. Oh now, what's wrong?
David: It was horrible. I thought they did somthing awful to ya. They`re green, had a ray gun and that fence was going.
Mom: What fence?
David: Across the sandpit.
Dad: Well, let`s go out and have a look.
David: It`s back now.
Dad: Well if it`s back and we`re the same, then you are dreaming, son.
David: I guess so...

A cut follows and David is back in his room, he wakes up, walks to the window and notices the UFO landing. Then the same ending as the German version's takes place.
