Other mistake: The titular baby elephant gets his name from the sign on his cot malfunctioning - the "D" in "Our Dear Jumbo" flips over onto the second line, replacing the "J." The problem is that as shot, there's no way for that to happen - either the letter's glued on and should have fallen off entirely, or it's screwed on and became loose, rotating around the bottom screw - in that case the D would be backwards.

Continuity mistake: When Holt's kids run to embrace him at the train station, watch the couple on the right (a man with a rucksack and a woman with a hat) are either standing still or walking away, depending on the shot.
