Die Feuerzangenbowle (1944)

Factual error: In the chemistry lesson on alcoholic fermentation there is written on the blackboard: H6P5O11 -> cane sugar, which is plain nonsense. (00:34:00)

Continuity mistake: Ackermann is asked to write names and biodata of important German writers on the blackboard when Pfeiffer enters the classroom late because of a fake toothache. When the camera is back on Ackermann he has completed the task in a fraction of the time he would have actually needed. (01:08:55)

Continuity mistake: When Pfeiffer and Knebel look through a fence at the effects of their putting up a signboard "School closed for repairs" the bars are different depending on the camera angle. (00:45:00)
