Continuity mistake: When Buddy is lying in the roll-out bed in the living room of his father's house and asks to be tucked in, his father does so. His father comes back up and ends up having a red thread on his shirt. The shot switches to Buddy, then back to him and the thread is now on his right arm.

Other mistake: Before Uncle Owen yells for Luke, if you look very closely, a fly can be seen on the lens (best seen on the special edition release). The fly was removed in the 2019 release.

Visible crew/equipment: After escaping the T. Rex, when Alan and the kids climb the huge tree we can see a bit of what looks like netting at the top right side of the screen and also the set's scaffolding at the left side, then after the scene with Hammond and Ellie in the dining hall, when it cuts back to Alan and the kids we can see much more of the netting behind the tree set, at the top of the screen.

Factual error: In the diner, the kids listen to/dance to Britney Spears' "Toxic," which didn't release as a single until January 2004. This takes place in 2003.

Other mistake: In the intro to the Pastoral Symphony, the narrator identifies the deity who cloaks the world with Night to be Morpheus, who is the Greek god of sleep and dreams. However, the character in the animation is fairly obviously female, with long hair, eye shadow, and lipstick. My theory is that the character was intended by the art team to be Nyx, the Greek goddess of Night. Night would be a more likely candidate to be making it nighttime across the world, while Morpheus would be more likely to put people to sleep or send them dreams.

Jake: The only reason I ain't signing is cause you've turned into some hoity-toity Yankee bitch, and I'd like nothing better right now than to piss you off.

Trivia: Disabled U.S. veterans would tell Gary Sinise that they were inspired by his portrayal of Lt. Dan in this film. Feeling humbled because he himself was neither a veteran or disabled, he established the Gary Sinise Foundation in order to help disabled veterans adjust to their new lives. https://www.garysinisefoundation.org.

Factual error: The sisters run out of fuel for the helicopter, which is then shown slamming down on the ground and essentially destroying itself. All helicopters are capable of autorotating safely to the ground in the event the engine(s) quit. Of course, that would not have been as dramatic. (01:05:15)

Continuity mistake: When Lucius is putting aftershave on in front of the mirror, he hears the robot outside and runs to the window, leaving the bottle of aftershave on the desk with the lid off. He returns to open the drawer, and the lid is back on. (01:29:00)

Question: What does Hu Li say in Chinese near the end, when she is holding the bomb that is about to blow up?

Visible crew/equipment: A boom microphone is reflected in Luke's goggles when he says "Hey, what's the matter? You smell something?"
