Visible crew/equipment: After Angela has set off the fire alarm at Cathedral & made the others leave, she checks the computer. She hears the fire engines outside, and walks over to the window. As she walks, we can see the camera rig reflected in the cubicle wall glass. (01:36:05)
The Net (1995)
1 visible crew/equipment mistake - chronological order
Directed by: Irwin Winkler
Starring: Sandra Bullock, Jeremy Northam, Diane Baker, Dennis Miller
Factual error: Angela Bennett finds the Praetorian's IP while using the PC in the Cathedral's bank: it's 23.75.345.200 - they want us to believe that this is an IP, but no IP can contain numbers greater than 255. [Common practice, like fake phone numbers, but still worth noticing].
Dr. Alan Champion: Will you be handling the outpatient care, nurse?
Angela: Well, do you mind?
Dr. Alan Champion: Visions of sponge baths dance in my head.
Trivia: The movie was a not so subtle plug for Apple/Macintosh. The director/producer Irwin Winkler is a "Mac man." All the personal computers Angela uses are Macs. Even at the end, the computer conference was filmed at the Moscone center in San Francisco and is a tribute/simulation to the main MacWorld conference which is held every January at the Moscone. The plot is based on the good guys using Macs and the bad guys on PC's/Windows. Still today, but especially raging back in the 1990's, was the huge Mac rivalry with Windows.
