Continuity mistake: When Michael runs into Barry in Reno, the envelope Barry is holding (containing money and a passport for George, Sr.) changes from a manila color to plain white. (00:14:15)
Visible crew/equipment: After Bob Loblaw suggests there may be a spy who is listening on secret information, the camera cuts quickly to everybody in the room individually before doing a wider shot. In this final shot, a boom mic is visible and is seen for about a second before being pulled out of frame.
Suggested correction: This is a well-know intentional joke in the show, relating to the fact they were being recorded.
