After the boat with Vereschagin explodes Vereschagin's wife runs crying along the beach. In one shot we see her having boots on her feet, but only a second later she is barefoot.
When the dynamite thrown by Vereschagin explodes and takes off the hats of the old men, the fourth old man is still resting his head on the box of dynamite that Sukhov had Petruhka remove earlier.
There are several scenes with four old men at the town square - three of them sitting and the fourth sleeping on his back just in front of them. The sleeping man's head rests on a wooden box which later is revealed to contain dynamite. The orientation of the word "DYNAMITE" on the box top changes between shots and, in one shot, the entire box disappears.
When Petrukha enters Vereschagin's house the laundry hanging on the left side of the stair disappears between the shots.
After the fist/gun fight where Vereschagin overtakes the gang members on board of the boat in one shot his clothes and hair are all wet since during the fight he was once thrown over board. His mustache is all wet with ends hanging down too. In the next shot his hair is dry and his mustache too with ends pointed up.
When Sayid offs two members of the Basmachi gang by shooting them from below his horse, he shoots twice in about a second, holding his weapon single handed. But the weapon is a Mosin-Nagan carbine that could only be reloaded driving the chamber lock manually which never happens here.
A PKM machine gun is seen several times in the movie (when the soviet soldier with Sukhov is pulled up into a house and again when a woman throws the gun into the sea) but it did not exist in 1920 when the plot is supposed to take place .The gun was invented in 1961.
The movie takes place in Turkmenistan circa 1920. At that time, Tukrmenistan had already become part of Soviet Russia (Dec-1917) and some residents began speaking the Russian language, but the official language up 1928 was Turkmen where an alphabet based on Arabic graphics had been used. Still all the signs and inscriptions seen throughout the movie are in Russian (Cyrillic) only.
The smugglers' boat is first shown on shore with the paint on her hull faded and worn down. The next morning, the boat is seen afloat in the bay freshly painted and loaded with goods. It is unclear how this happened since the Basmachi gang was busy throughout the night hunting for Sukhov and the harem.
