Audio problem: When we are introduced to Passepartout riding a monocycle a man inside a carriage cries "Move over, son!" but his lips don't match what we hear.
Audio problem: When Passepartout dances flamenco the tambourine player is out of sync with the music playing. After a while he even stops playing it but the music keeps going on.
Audio problem: When they arrive in Spain, Passepartout speaks to a Spaniard, whose heavy foreign accent shows he's not Spanish (it was Italian born and USA citizen Constanzo "Jose" Greco). It is so obvious and lame that his Spanish voice was dubbed with a real Andalusian accent in the Spanish release.
Audio problem: When the balloon starts rising Fogg cries "Passepartout! Come on, man!" but his lips aren't moving.
