The Water DivinerGoofs
Errors in geography
Movie shows clearly that Connor enters Istanbul through the port of Haydarpasa (at the Asian side of the city). The boy drags him to the hotel which is supposed to be around Sultanahmet (European side). This is verified by the boy's comment "Sultanahmet, we go!" and with the camera shots several times downhill from the hotel with a clear view of Galata tower from the old city. The problem is; Connor follows the boy running from Haydarpasa to Sultanahmet in a couple of minutes, which is impossible due to the Bosphorus waterway between the Black sea and the Marmara sea passing through the city. (They should have taken a boat).
The dust storm in which Connor rescues his young sons is used to dramatic effect in the movie, but is neither particularly common nor life-threatening in Australia in general or the northwestern area of Victoria where the Connor family were farming. Bushfire and grass fires are a far more realistic and common threat, which most definitely could have caused a dedicated father like Connor to gallop off in search of missing children.
The British Occupation troops in Constantinople/Istanbul are armed with very rough and obvious mockups of the fully stocked .303 caliber Short Magazine Lee-Enfield rifles which were correct for their unit and period. "Giveaways" making the mockups obvious include: wrong bolt action; lack of the large charger bridge on the action; lack of the distinctive protective "ears" on the backsight; two fore-end bands where the real rifles had only one; incorrect buttstock; incorrect profile of the distinctive angled 10-round magazine which projects below the action on real SMLE rifles. Presumably mockups were necessary because armourers could not source sufficient stocks of the correct model of Lee-Enfield rifle in Turkey.
On the battlefield, right before Art shoots Henry, Art takes a look at his dead brother Edward. The first close up of the face shows that the face is completely shot off, including the eyes. The second close up (a little bit further away from the body) shows the face, but here it is less damaged, e.g. the right eye isn't damaged.
