Factual error: The brothers are in a hotel room. Joe Newton is seen counting money using a "Baby Calculator." This particular calculator was manufactured by the Calculator Machine Company of Chicago, starting in 1939. The Newton gang's crime spree was from 1919 up until 1924 when they robbed the train outside of Chicago, so he was using a calculator that didn't exist yet. (00:30:30)
Continuity mistake: Rosina is meeting for tea the fish trader that she is supposed to marry. Her mother hands her the plate with cake, she takes it in the first shot, but she is taking it again in the following. (00:10:15)
Other mistake: Christopher Reeve's nurse has just installed the camera, and they are showing it to Daryl Hannah. During a close-up of Jason Kemp's camera displayed by a monitor, she notices that the woman victim of domestic abuse is wearing too much make-up for that time of the morning, no doubt to hide the results of the beating she took. Jason does not move the camera at that point, but a minute later he (it actually looks like she is the one doing it, but there's an engine buzz so it should be Jason operating it, not her turning it by hand) rotates it to the right. The visual in the monitor is unchanged from earlier even if the camera moved. (00:33:30 - 00:34:30)
Other mistake: The color of the buttons described by Diderot (and as it can be seen on the schematics he's holding) does not match the actual control panel of the crane. (00:05:00 - 00:06:40)
Continuity mistake: When Lee and Chris go swimming they briskly towel off still a little wet. Yet a few moments later they're completely dry.
Other mistake: In the scene where Vir gets in a fight with Zack you can for a moment see the Rolex that Stephen Furst is wearing on his right arm. (01:21:10 - 01:21:20)
Factual error: When Victor and Thomas are riding on the bus from Idaho to Arizona, the same driver is driving the bus the whole trip. In reality, the driver would have changed a few times on such a long trip.
