Continuity: When Briony sees Cecilia coming out of the fountain (from Briony's perspective), Cecilia steps out of the water with her right foot first. When we see the same scene afterwards, from Cecilia an Robbie's perspective, Cecilia steps with her left foot first.

Continuity: When Cecilia and Robbie are having sex against the bookcase, a close-up reveals she slips her left foot out of her shoe. But when Briony walks into the room and the two lovers are shown motionless, we see Cecilia still has both shoes on. Submitted by John W Rosa

Factual error: In the section of the movie set in 1935, there is a scene where Robbie is daydreaming and the image of a four engined bomber crosses the screen. The image is of a Short's Stirling (the tail configuration is markedly different to the Lancaster), an aircraft which did not enter service until 1939. Submitted by www.translingua.com.mx

Deliberate "mistake": In the approach to Dunkirk, Robbie is carrying a pistol, complete with webbing holster. He has no rifle and is carrying a bayonet on his haversack, presumably not having the usual belt frog to carry it more easily. As a Private (this is emphasized in the dialogue) in an infantry regiment, he'd have carried a rifle and not a pistol. Although he might have acquired the pistol during the retreat, he's less likely to have changed his webbing order to match. This may be a deliberate directorial choice. The dialogue emphasizes his natural "officer qualities", and that his prison record has prevented him from becoming one. The wearing of officer's equipment, even if historically inappropriate, also reinforces this and distinguishes him from his comrades. Submitted by www.translingua.com.mx

Continuity: In the love making scene in the library, Robbie pulls down the strap of Cecilia's dress and she pulls her arm out. In the next shot it is up and over her shoulder again. Submitted by www.translingua.com.mx

Factual error: On arriving on the beach at Dunkirk, Robbie is told of the sinking of the Lancastria and the loss of 3000 men. This event actually occurred 17 days later on June 17 1940. Submitted by www.translingua.com.mx
