Audio problem: In the scene where Victor plays the piano for the first time in the movie, we hear him playing long, sustained notes, which obviously need to be played with a pedal down. However, he doesn't use the sustain pedal. What's more strange is, the piano does not even have a sustain pedal.
Audio problem: When "Randy Newman" is playing the piano in the beginning, it is completely visible that the piano hammers aren't moving at all.
Audio problem: Near the beginning, when the two metal monkeys strike the Central Park Zoo bell, it makes two different tones. As it's the same bell they're hitting, and they hit it at the very same vertical axis, it should make the same tone both times.
Audio problem: In the scene in the church where Tifa and Marlene are confronted by Loz, Loz approaches the two as he's talking and his boots are easily heard on the wood. When he notices the flowers, the scene shows, as he's looking down and the flowers are surrounding him, that the wooden floor is gone. When he asks, "Where's mother?" he takes a step forward and his boot is heard on wood. A few seconds later he takes another step, followed by the same boot on wood sound, when there shouldn't be any wood below him.
Audio problem: During the scene where Jack Hammer is sold out, the 'bin robot' says 'Hey, isn't that the guy that fixed Fender's neck?' Next someone in the crowd says 'Yeah, that g-ixes bots!' The phrase should be 'Yeah, that guy fixes bots!' There seems to be a half-second clip that is missing in the film.
Audio problem: In the scene when Grandma is at the tournament (but not yet skiing), in the cuts when the band isn't visible, if you listen closely, the lead singer isn't singing. (01:05:05)
