Origin Of The Iron Giant (spoilers)

Rating: 8/10 (3 January 2006)

The review says how the origin of the Iron Giant is unknown (even to him).
But it's not true.
A deleted scene from the movie (included on the DVD) shows what the Iron Giant was intended for, if not the specifics of his creation.
The Iron Giant is dreaming and his dreams are broadcast to a nearby TV. It shows an army of Iron Giants (in weapons mode) marching on a planet. They start destroying everything in sight. Then we see the Iron Giant (the one who comes here) look at his shadow, a precursor which hints at his destructive potential. Then the Iron Giants use their chest weapons and the planet blows up.
At this point, the Iron Giant wakes up and the dream stops. The only thing that is not specified is how he came here (or why).
