Continuity mistake: When Solo begins trying to seduce the dancing girl with the line, "We shall taste paradise," he's standing at least a foot away from her. But in the very next shot, they're suddenly in a clinch: her hands are on his cheeks and they're about to kiss.
Continuity mistake: At the end, Solo and Illya are sitting at a small bistro table as the captured bad guys are marched past them. Solo wears a green fez, and between shots, Illya suddenly acquires a red one. It wasn't in his hands or on the table before that: it just seems to appear on his head out of nowhere.
Continuity mistake: Delgado's plane makes a bumpy landing (without a runway) and skids to a stop in the Brazilian jungle, surrounded by palm trees. But when everyone gets off, the plane is suddenly parked in the midst of an industrial compound with buildings all around it, and no palm trees in sight.
Continuity mistake: In close-up, Illya is covering the phone receiver with his left hand, but drops the hand to his side when he tells the operator, "Never mind." There's an immediate cut to a wider angle, and his left hand is suddenly back on the receiver in the same position as before.
Continuity mistake: Pendleton swallows a suicide capsule and collapses at the interrogation table face down between two file folders. But when the shot cuts to a different angle, his head has instantly moved several inches to the right and is resting in the middle of one of the folders instead of in between them.
