Directed by: Christopher Nolan

Revealing mistake: The ship set up for the capsize scene is supposedly mid channel and heading for England when it is bombed by the Heinkel, but it is at anchor.
Revealing mistake: In some of the shots where multiple British soldiers are together, most have their rifles (Short Magazine Lee Enfield, No. 1 Mk 3) slung or are holding them. Some of the rifles are dummy, toy rifles that look nothing like the Enfield and are just to stand in.
Factual error: In the scene towards the start of the film in Weymouth harbour, you can see the huge building which is Weymouth Pavilion, which was built in 1954, after the original 1909 building burnt down.
Lance-Corporal: The tide's turning now.
Colonel Winnant: How can you tell?
Lance-Corporal: The bodies are coming back.
Trivia: There are only two women with speaking parts in the whole film, with 47 words between them.
Question: A few minutes into the movie you see English troops all lined-up on the beach with no obvious means of evacuation. That leaves them very exposed to German gunfire and aerial attack. It would seem that the English soldiers would stay off the beach until actually called-up for evacuation. Not to mention the obvious requirement that some troops would have to stay off the beach to defend the evacuation area. How realistic are those scenes?
Answer: That's exactly how it was. If you search for images of the evacuation, the troops were stood in lines, waiting to be evacuated. The Germans were held at bay, and the air raids were periodic, so there was little risk on the beaches.
