Factual error: At some point during the marriage of Juvenal Urbino and Fermina Daza, Dr. Urbino visits Florentino Ariza's office to ask for a donation from Florentino's uncle for a musical charity event. He asks Florentino whether he likes music, and Florentino answers that he likes the music of Carlos Gardel. A few scenes later, the town welcomes the arrival of the year 1900. Tango singer Carlos Gardel was born in either 1887 or 1890, and did not reach fame until the 1920s, so it is impossible for Florentino Ariza to have heard his music before the year 1900, when Gardel was, at the most, only 12 and not yet into singing.
Factual error: Early in the film, Chris foils a casino shooter, steals a car, and leads police on a high-speed chase through Las Vegas. He has a psychic vision of himself being smashed into oblivion at a railroad crossing, so he knows he must accelerate to 120 mph to beat the train. The camera cuts to a head-on view of the train, and this time Chris goes flying over the crossing, just barely missing the train. Oddly, there are no barricade arms with warning lights at the railroad crossing, even though this train is screaming through an urban area. Additionally, the car is already levitated about 3 or 4 feet in the air long before it ever reaches the railroad crossing, as if it hit an invisible launch ramp. Thus, Chris makes his escape as the train blocks any further police pursuit. We then see two angles of the fleeing vehicle suddenly make a hard left turn down a side street about a block past the railroad crossing. Which is physically impossible. Given that he air-jumped the railroad crossing at 120 mph, Chris could never have slowed down enough to make a hard left turn within one block. It would require more like 10 blocks to slow down to a manageable turning speed, if he could regain control of the car.
Factual error: In the scene showing Septimus swimming underneath the water after having dived through Capt. Shakespear's cabin window, you can see Septimus holding his fighting knife in his right hand. After a stroke or two he lets go of the knife and it doesn't sink.
