Character mistake: The movie starts with shots of the moon Io and the company's operations, with typed descriptions at the bottom of the screen. Guess they couldn't afford a proofreader. They spell dependents as dependants, marshal as marshall, and principal as principle.
Character mistake: When the revolutionary fighter commandeers Air Force One (we only know this once she's in control), a Secret Service agent is trying to break down the cockpit door by banging it with the butt of his automatic rifle. The way he's hitting the door, he couldn't break through a cereal box - it's much too weak. Presumably, the actor is taking it easy on the door because it's a cheap prop door. (00:11:15)
