Factual error: The picture of Eddie and Teddy on the road with dad, supposedly taken in 1906, shows a Ringling Bros and Barnum & Bailey circus poster. In 1906, the Ringling Brothers circus and the Barnum & Bailey circus were two separate circuses playing in different parts of the country. They did not combine the two shows until 1919. (00:27:00)
Continuity mistake: During the "Why Should I Worry" song, Dodger goes with his "scarf" of sausages through a basin full of wet cement. Logically the cement should be stuck on the sausages, though that does not appear to happen, even though the sausages went through the cement. There is cement on his paws, though, that he needs to wash off.
Continuity mistake: When Petri fell into the tar pit, there were two dinosaur skeletons, one on each side. When Spike, Ducky and Littlefoot went to rescue him, the skeletons were gone.
Continuity mistake: When Kaneda shoots Tetsuo with his laser gun, it makes a hole on his shirt. In the next scenes, the hole is gone.
Other mistake: When Satsuki enters the shot when she, Mei, and their father visit their mother in the hospital, Mei seems to be constantly staring up at their mother with her mouth gaping wide open.
Continuity mistake: When Garfield is entombed within the pyramid, Odie comes along and frees him by dislodging one of the pyramid wall's stones - the second one nearest the corner. But when viewed from Garfield's perspective an entirely different stone is missing from the wall, about two spaces closer to the wall's center. (00:12:15)
