When Hendrik begins reading the diary the desk lamp is on his right, but when Geoffery turns it on, it is on Hendrik's left. No one has moved it in the mean time.
In the workroom where Stephen is repairing his race car, the words "NON FUMAR" are written on the wall, with the English words "NO SMOKING" beneath. The Spanish is incorrect: it should read "NO FUMAR".
At 1 hour, 12 min, as Stephen is driving his race car on the first leg of the race, flames can be seen at the bottom of the screen, although his car does not catch fire until the second leg of the race, on the way back.
At 1:18:49 the trombonist's drink is sitting tilted on the beach, but the contents are also tilted. Liquids always lay FLAT.
Most of the story takes place in 1930, but the costumes and hairstyles of Ava Gardner, as well as those of Sheila Sim and Pamela Mason are strictly in the 1950s mode.
According to a banner at the event, the (wheel-driven) land speed record breaking attempt occurs on August 20, 1930. The narration states that Cameron will have to average more than 214 mph. However, the real land speed record at that time - set more than a year earlier, on March 11, 1929 - was 231.446 mph. Beyond this, the thought of Cameron attaining the speeds he does in a car with the unmodified body from an open wheel race car of the time is rather absurd: specially built bodies were already being built to reach these speeds in the 1920s. Beyond the aerodynamic considerations for speed, a potentially even larger problem was creating downforce to provide enough traction at these speeds.
