Factual error: When the helicopter crashes in the water, it is most obviously dropped straight down from a crane. Even though it ran out of gas, the rotor blades would still be turning somewhat.
Revealing mistake: The same scene is used as two separate shots when Pacino hits the lawyer's windshield with his briefcase. One view from the inside the car then from the outside.
Visible crew/equipment: In the helicopter scene, the shadows of Pacino's helicopter and the filming helicopter can be seen on the water surface.
Visible crew/equipment: In the scene where Forsythe grabs Pacino and shoves him up against the wall in his office, Pacino's microphone can be seen under his tie. (DVD). (00:41:50)
