From 34:00 to 36:00, when Dr. Simon Kurz goes into his office and throughout the scene, his door is on the left side of the office and the door's handle is on the right. After Bruce Ivins swabs the right side door handle and thereafter swabs the entire office, he leaves through a door on the right side of the office with a left side door handle (36:28). Various shots throughout the scene show that there is no other door than the one. The flag and the nameplate are not reversed.
At the airport scene in the beginning, in the background is a Boeing 737 with the split "scimtar" winglet on the left wing. This was not available until 2014, while the scene takes place in 2001. The right wing does not have the the same winglet, likely taken out in post production while the left wing was mistakenly overlooked.
