Continuity: On the ship, the female fighter is wearing boots; when shown resisting arrest, she is wearing sandals.
Miscellaneous: At take off we see an Eastern Airlines Boeing 727, a narrow body aircraft (with one aisle). However, the shots inside the aircraft show a wide body aircraft (with two aisles), and this cannot be inside a 727!
Continuity: At the start of the movie Terence Hill is wearing a St-Louis Cardinals cap. When he arrives at the truck stop, he's wearing a Red Sox cap. at the hotel's bar he's seen again with the St-Louis cap. When he goes out to the Marineland park he wears the Red Sox cap.
Audio/visual unsynchronized: (At 35:00) The helicopter seen is a Bell 206 Jet Ranger, which is equipped with a turbo-shaft engine (a form of jet engine / gas turbine, optimized to produce shaft power, rather than jet thrust). But when the engine starts, the sound of a piston engine can be heard instead.
