Continuity mistake: In the sequence with Terence Hill and Marvin Hagler giving chase to the bad guys, when the baddies break the guard-rail and supposedly drop one level, the lights of the chasing car are still fully visible through the back window before the good guys take the same dive from the highway ramp.
Factual error: In early scenes, Lieutenant Commander Ramirez is wearing insignia for Lieutenant, not Lieutenant Commander. Later scenes have him wearing the correct insignia.
