In the safe-house Abbas Naziri is making coffee with a percolator, which is instantly ready, where normally this would take at least a couple of minutes.
On Hanna's second visit to the safe-house to see Naziri. When he walks into the kitchen the milk bottle on the table can clearly be seen with a red lid on top of it. However, when he sits down at the kitchen table the lid has disappeared, even though the bottle has not been touched by either character.
When Hanna goes back to finish off the killer, she fires the gun but the slide never moves and no bullet casing is ejected. In fact, the gun never moves at all.
At 39:05, when Hanna pulls the trigger, there's sound but no muzzle flash.
