When Donloe the computer technician enters the vault after his unfortunate coffee break, we see him opening the door and stepping in onto a white floor - however, the next shot from above shows a shiny black floor, as it should look when countermeasures are off (it's the same shot where Ethan's reflection is missing).
At the end of the movie when Ethan and Luther are sitting having a drink outside the Anchor Pub in Bankside, they are sat at tables located in a place that would not be allowed by the local council because they would be obstructing the right of way. The only outside tables allowed at that pub are those located on the riverside podium - which can also be seen in shot.
When Ethan makes the phone call from Liverpool Street Station the phone number being traced is a Knightsbridge number and not a Liverpool Street number.
Where is the "Akvarium" restaurant that Ethan blows up with the gum?
A
It doesn't exist, it was a set constructed for the movie & specifically for the scene. As Ethan escapes from the rushing water he runs north through Prague's Old Town Square, which is a real place. Through careful cinematography & editing, it appears that the place is in the Old Town Square. To enhance the effect, a large quantity of water is even dumped onto the pavement behind him.
