Plot hole: Solo hopes that Elfie can fly the helicopter they're about to escape in. Why? It's a standard-issue helicopter: nothing special. Did both he and Illya, who've flown many 'copters in previous episodes, suddenly forget how?
Factual error: Both on the superimposed title of Act II, and at the airport on the large printed sign attached to the animal carrier, the word aardvark is misspelled "aardvaark."
Continuity: Joanna learns from the hotel waiter that he saw Illya and a chambermaid going into the woods. But she later tells Illya that she saw him leaving with the girl, and goes on to describe the chambermaid - a person she never saw.
Continuity: The remote-controlled model plane with the explosive on board keeps changing colors between shots. It's yellow and blue at first, then yellow and red, and in one shot, it's red and white.
