Factual error: Toward the end, Einstein holds a Rubik's cube. A corner piece has two orange faces (not possible). It appears again about a minute later.
Factual error: When the car goes to the bottom of the ocean after the chase, the water in it is raising as if leaking in, despite the fact that the door on Hiro's side is missing and the water should be rushing in. (00:50:15)
Suggested correction: I watched the scene and it looks like it's filling up the way it should. It's looks similar to the way a car fills up after being submerged with the windows open.
Not true, water is still filling up the car way too slow for an opening like this. The car should be filled up immediately.
You're wrong thinking it would fill up immediately. But even so, it fills up in about 10 seconds (even less if the shot of it filling up is meant to be a simultaneous shot and not continuous).
Factual error: The unit on Dusty's torque dial appears as FT/LB (i.e., FT divided by LB) which is incorrect. FT.LB (i.e., FT times LB) is a unit of torque.
Factual error: After Batman hits the Manbats with his sonar batterangs and they go nuts trying to escape the sound, some begin chewing at the glass separating them from the ocean in their desperation. This is in the under workings of an oil rig out in the ocean. Hundreds of pounds of pressure is on that glass. The Manbats chew through the glass, and then the water begins rushing in. All logic and laws of physics dictate that the Manbats would be pushed back, down into the oil rig further as water rushes in. However, as the water begins pouring in, 3 Manbats are somehow pushed out of the hole into the water, and are sitting still, long enough for a shark to grab one. Even if they did somehow manage to get out like that despite physics, the water rushing in the hole would have caused a vacuum and sucked them right back in. Yet they remain perfectly still in the water, only a couple feet or so away from the hole they just made.
