Corrected entry: When The Equalizer exits the large home in Russia, the two Range Rovers flanking the entrance have European Union tags rather than Russian plates.
Corrected entry: Denzel Washington's left hand is injured during the fight scene in the Home Mart, but near the end of the movie when leaving Pushkin's residence, his right hand is bandaged.
Correction: When he's lying on the floor after the fight with the guy with the massive beard, the shard of glass is in his right hand so it's feasible both hands were injured.
Corrected entry: Just before Robert kills the arch villain, he has his friend the security guard turn on all the lights. After killing him, Robert turns around and walks into the dark warehouse.
Correction: The lights go out when the alarm goes off and the explosion disrupts the cables, so then we are back to the emergency lights that are only lit in certain parts of the store.
Corrected entry: When Robert attacks the first hostage holder in the warehouse, blood comes out of his victim's mouth and nose and touches the floor. In the next shot, when Robert drags him into the security room, there's no blood on the floor.
Correction: If you watch closely you will see blood on the floor and a little drag mark from the blood also.
Correction: You can't really tell that the plates are from an EU country, they don't look Russian granted, but even so, cars get imported all the time. I saw a really nice Mustang just the other day with its original US plates on here in England.
Depending on picture quality and screen size, it is easy to see that the plates are from Ireland (IRL in blue field). So yeah, I'd rank it as a mistake ;-)
