In one level, Bond looks through the scope of a sniper rifle and sees the three villains of Diavolo, Yayakov and Katya. He however doesn't use the opportunity to shoot/kill any of them (if he did it would be the end of the game already).
The levels with the places in New Orleans, Louisiana or the Red Square in Moscow, Russia are mostly wrong. (video games are known for having geographical inaccuracies unless the game wouldn't be that fun).
