Other mistake: Near the end of the closing credits, when the Warner Bros. Copyright appears, you'll see the very first word "All" spelled incorrectly as "Al" in "All material is protected by Copyright Laws of the United States and other countries throughout the world." (01:26:40)
Other mistake: The first "All Dogs Go to Heaven" was set in 1939 and Charlie died that year. When Itchy joins his pal in Heaven, it is obviously the 1990s. Are we expected to believe that Itchy lived for over 50 years compared to other dogs? If so, why isn't he extremely old when he finally arrives in Heaven?
Other mistake: While Iago talks to the Oracle, when he flies towards her, he's seen not flapping his wings; he's just floating.
Other mistake: When the bus starts to leave the Hoover dam (as seen through Dallas' binoculars), the driver is missing. The steering wheel is shown with no-one behind it.
Other mistake: During the "Hellfire" sequence, when Frollo is singing "God have mercy on her, God have mercy on me...", his shadow against the wall behind him rises as he backs up closer to the wall. However, when he turns around to press against the wall, his shadow ends up far above his body when it should have become level with his body by that point - like the very next close-up shot of Frollo shows, which is itself a continuity error.
