Continuity mistake: During the climax, when the old-fashioned Atari-controller is lowered down from the UFO, watch closely. In the first two shots, it's swinging back and forth rather quickly and dramatically, however, immediately from the third shot on, it's suddenly barely swinging. It's too instantaneous between edits to be the result of it naturally losing momentum.

Hayden Christensen is still standing up with rain falling around him.

It's still a wide angle, but you can see distinctly both her and his left arm stretched forward; she is looking at her engagement ring, he has his hand on the steering wheel. Before the camera cuts away though, he lowers his arm; it is not acknowledged in the new shot, where both have still their left arm forward. (00:03:35)
