Other mistake: While the fire on the oil rig burns all around, Mr. Freeze grabs Belson, then orders him to go find Barbara (to do the transplant). When it cuts to a closeup of Freeze, the reflections of Belson on Freeze's eyeglass lenses are not reversed as they should be. (00:53:00)
Other mistake: Freeze uses his gun to extinguish the fires on top of the elevator, and that somehow gets it back to work, but it does not really make sense. His gun greatly weakens metal, as shown earlier, to the point of breaking it, and he did not shoot the engine of the elevator, which is what was shown malfunctioning.
Other mistake: Freeze gets in sight of the toll booth (we see the headlights from his truck on the asphalt before it), and there's a car in the outer lane he is travelling in, but he has a (too) long and uninterrupted run in that lane. That aside, the road goes from having 4 lanes to 3 lanes and back to 4 lanes, and everyone is going at mad speed having barriers this close (especially with the toll booth not being automated). (00:27:00)
Other mistake: When Dr. Belson searches the blood donor database, a lot of weird stuff happens; first of all, he is searching it by name, and it's the name of Mr. Freeze's wife. Since for some weird reason she is shown later being in the donors database (doubtful that someone with an incurable disease would be a donor!), it should return the information about her, but it does not. Secondly, he is opening the database search again once Freeze promises the gold vein, and the form shows already the personal data of Nora but without her name this time, and including the blood type, which he types only in the next close-up. (00:20:50)
Other mistake: Freeze's hideout is in an abandoned oil rig, with its tanks full to the brim of oil. You'd think the company owning it would have drained the millions of dollars' worth of content first, before 'abandoning' it.
Other mistake: When Bruce Wayne is searching the database after the nurse leaves Dick's room, the screen initially has the vital stats (height, age etc) of Nora, Mr. Freeze's wife. (00:32:00)
