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)
Continuity mistake: When the two cats move past the yawning rat to go up the crane lifter, the door is shut, but they slip into its semi-opened door when they reach the platform in the next shot. (00:06:05)
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)
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.
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.
Continuity mistake: In the final lap of the race with Pre vs. Frank Shorter the two runners round the last lap with Shorter leading the race. At first Shorter is leading in lane 1 with Pre following directly behind. Then Pre is suddenly in lane 2. For the final straight away, Shorter is now in lane 2 and Pre in lane 3. (Also a factual error as no runner leading a race would ever run in any lane other than the first which is the shortest distance). (01:36:00)
