Audio problem: In the Governor's office, as Clayton was recording a memo, Benson complimented him, saying, "Nice work, Clayton." However, if you listen closely, you notice that Benson's voice ended on a higher note than on the recording.
Visible crew/equipment: As Benson, Kraus, and Clayton go to leave President Voorhees, and as they cross the first area, if you watch the top of the screen, you briefly see the boom mic following them.
