The Germans - S1-E6
Visible crew/equipment: When Basil runs from the restaurant and into the office, as the door opens to the hallway you can see a monitor in the office, showing what we can see. The director must be watching the action from in there.
Suggested correction: Most places like this are likely to have CCTV and the office would be the optimum place for the manager to watch on the monitor.
CCTV was very uncommon in 1975. It wasn't until the late 80s it became more popular and even then it was of poor quality. Not like what is in the mistake.
