Suggested correction: There is no casing on the bullet.
Factual error: As Klaatu is walking down the train platform at Newark Penn Station, in the background you can see signs that say "VIA". VIA is the national railway of Canada and does not have a presence in New Jersey. This scene was filmed in Canada, as evidenced by the signs on the platform and the 1950s style streamlined passenger cars on the track. Neither Amtrak nor NJ Transit uses those type of cars in their trains.
Klaatu: There are some things I can't do.
Jacob Benson: But you have powers.
Klaatu: I'm sorry.
Jacob Benson: Please. Please!
Klaatu: Jacob, nothing ever truly dies. The universe wastes nothing. Everything is simply, transformed.
Jacob Benson: Just leave me alone.
