Revealing mistake: When Col. Franz von Waldheim first encounters Mademoiselle Villard at the museum and walks away from her to turn on all the lights, the wall to the right bounces like canvas as he operates the switch.
The Train (1964)
1 revealing mistake
Directed by: John Frankenheimer, Arthur Penn
Starring: Burt Lancaster, Paul Scofield, Jeanne Moreau, Suzanne Flon
Other mistake: Labiche uses binoculars to view the coupling of the armament train from the control tower (when they are deliberately delaying train coupling), but the binoculars are in the closed/stored position, lenses close together. You cannot view through them like this as they don't line up with your eyes. In a later scene, when Papa Boule is driving the train through an air raid, he uses the binoculars correctly in the open position.
Colonel von Waldheim: Beauty belongs to the man who can appreciate it.
Answer: This appears to be continuity or editing mistake where the binoculars suddenly disappear.
