Audio/visual unsynchronized: During the scene in which Hans' friends menace Cleopatra in the wagon, the flute soundtrack doesn't match the finger movements of the dwarf playing the flute.
Continuity: Hercules rushes out of the wagon in pursuit of Josephine/Joseph, hot on his/her heels, but when Cleopatra looks out the window a moment later, Josephene/Joseph is leaning casually against a wagon applying makeup. He/she would not have had time to relax and get out a compact in that short amount of time.
Boom mic visible: The shadow of the boom fall on Phroso's back when he and Venus are talking in the trailer, after her angry outburst at him.
