Continuity mistake: When Ava is in Yuri's trailer discovering all the guns and things, Nicolai is shown behind the blue things hanging from the ceiling. It cuts to a close up of Ava, then it cuts back to where you can see where Nicolai was standing, but he is gone. It cuts back to Ava and then back again, and he is there.
Continuity mistake: During the opening credits when the camera is following the bullet. When it is loaded into the gun magazine three other bullets are loaded in after it. However, when the gun is being fired, twelve bullets are shot out of the magazine before the one bullet is next to fire.
Continuity mistake: Yuri is standing at the stern of the ship ordering the name change to Kono. He takes his binoculars, looks out to sea, and sees the navy approaching. But in the next shot we see the navy ship approaching from the bow of Kono so Yuri could not have seen it approaching from the stern.
Continuity mistake: After changing the name of the freighter from Kristol to Kono, there is a moment where you see Valentine's perspective as he examines the name on the stern of the ship. For some reason in this shot, the K in Kono is inverted.
