Factual error: When Joe and his girlfriend, who is also Albert White's mistress, walk through the hotel room kitchen, that whole kitchen, is not a 30's era kitchen. It even has a convection oven and a blast chiller, pan racks, etc. that are more from this time.
Factual error: During the scene when Ed the I.T. guy is working on his laptop to fix the problem with the presentation, his laptop is sitting on top of a couple of Cisco network switches with cables connected to them. The ports on the front of the switch where the cables are plugged in would have flashing lights on to show power and connectivity, as well as lights on the left-hand side of the device as we are looking at it, no lights are present which suggests it is not powered up and connected to anything.

Factual error: In the wedding and arrest scene the U.S. Customs Service officials have police attack dogs. The U.S. Customs Service only has drug detection dogs. (01:57:00)
