Revealing: The ship is supposedly pitching heavily in stormy seas. But because the tilting effect is merely the camera moving, the whiskey bottle, glass and other items on Captain Morton's desk don't slide or fall off. In fact, they don't move at all.

Factual error: The intro screen says we're in Hong Kong as a ship with Illya trapped aboard steams out of the harbor. We then cut to an exterior shot of the ship departing what we've just been told is Hong Kong - with, unmistakably, the Golden Gate Bridge in the background.

Continuity: The ship we see steaming out of Hong Kong (with Illya aboard) is shown later out on the open sea - only it's not the same ship. The first was painted black: the ship we see later is white.

Visible crew/equipment: During the fight aboard the plane, Solo's stunt double's face is fully visible several times.
