Factual error: When Jackie pulls out the unusually high amount of cash that Simon happened to have on him, you can read the banknote was issued in 1940. The movie is set in the 1930s. (02:08:40)
Suggested correction: 1) The shot is onscreen for a fraction of a second. 2) Even using freeze-frame, I do not see any visible date. Do you have a screen capture of this?
I did not, but I took one for you.;). I just uploaded a zoomed-in and straightened version you prolly can already see in the pending screenshots section. It says "Juin 1940", but you shouldn't need it; the note is on screen for a full second or slightly less, but the fact that allows you to read it without even pausing is that she holds the note straight, her motion stops just long enough to avoid stealing the moment with freeze-frame (in fact if you take screenshots on VLC like I do, the compression might make it harder to read than watching it in real time). And also pre-WW2 1000 Franc notes have a huge date, I circled it for you in the screenshot. You can also notice the signature of the "caissier general" that matches notes post-summer of 1937 at earliest, and the only date given in the movie is 1930. Serial numbers are consistent with a 1940 release as well, they definitely used a legit banknote from the era who happened to be a late print.
Other mistake: During the denouement, there is a scene with the meeting between Simon and Jacqueline inside the doctor's cabin. Jackie opens the doctor's case where he keeps the surgical tools pulling it out from a drawer, and she does not place the box back in the drawer or closes it; we see the whole time she spends inside the cabin, so it'd be impossible for the doctor not to notice what happened.
