When Damien breaks a Chinese vase, the fat Chinese mobster says "this a 12th Century Ming vase" (and Damien replies that the true one has been returned to the museum). Actually, the Ming dynasty began in the 14th Century.
When Letto pulls the cable from the laptop into the server it leads directly into a hard drive, on servers there are no cables at all that lead into hard drives from the front, ever.

At one point, the main character is using what seems like a monocular telescope to oversee the situation. The next shot confirms this when the screen shows as if you were looking through one. However, the device used is not a telescope, but a night vision monocular. Not only the model can be recognized (it's of "Yukon" brand), but also the 2nd (smaller) lens on the device, which is actually a IR emitter. Using this device at day will not allow to see very much. Moreover, the following shot of the telescope view should be green because thats what one sees when viewing in night vision.
