Murder in Montparnasse - S1-E7
Factual error: During scenes in the kitchen (when Bert and Cec hire Miss Fisher; when Butler the butler advises Dot about dealing with the hypocrite priest) a wall calendar is featured. It's nice that it shows the month of October, consistent with the continuity of the season, but it's not an October 1928 calendar, the days are all wrong. (00:21:25 - 00:27:15)
Other mistake: Miss Fisher takes a handwritten phrase in "ancient" Hebrew to one of the main characters to be translated. The writing is actually in cursive Hebrew and is properly written. While performing the translation however, the "expert" translator holds the writing upside down. He also follows the writing with his finger from left to right. Hebrew is written from right to left. (00:32:00)
Suggested correction: When reading Hebrew upside down, tracking from left to right is actually the correct way. Of course, reading this way in the first place is extremely weird, at least.
