Continuity: When Rankin Fitch meets the gun company guy who is shooting clay pigeons, near the end of the conversation, the gun company guy starts to put on his safety glasses and says "Pull" before he has time to shoot, but in the next shot, he is fully prepared, and hits the target in the air.

Continuity: As the funds are being received at the Cayman Island Bank, the issuing bank name and address is filled in as "Cayman Islands Reserve Bank", however the printout of the transfer has issuing bank name and address as "Bahamian Reserver Bank" in Nassau, Bahamas.
Revealing mistakes: When Fitch is viewing a video of Nick, we see it paused with embedded timecode paused along with the video. the last two numbers (:39) indicate the frames, not seconds (you can tell this by the speed at which the numbers run and the fact the "tens" number never passes 3) when in play mode. Frame rates for NTSC (north American video) is 30 frames per second, anywhere else in the world it varies, mostly at 25 frames/sec in most of Europe, but no video is more than 30 frames/sec.
Continuity: When Rohr has hired Lawrence, he steps in his car. Lawrence is standing next to the front tire. In the long shot of Rohr pulling out, Lawrence is standing a few feet back and has turned around.
Continuity: When Fitch meets the gun company men, a chessboard is shown. The game is already started (the white Queen and the white King are in wrong start position). In the next shots, after some seconds, the chessboard shows the chess pieces in the start position (and the white Queen is finally in the correct square).
Revealing mistakes: When Marlee supposedly jots down her e-mail address for Fitch on the street car, she uses about 2 or 3 pen strokes, which is barely enough for her to write "@" much less an actual e-mail address.

Errors in geography: When the investigator is in Gardner, Indiana speaking to Marlee's mother, you can clearly see the spires to the Crescent City Connection in the background. This reveals that the filming of that scene actually took place in New Orleans.
