In Which We Meet Mr. Jones - S1-E7
Visible crew/equipment: During the shot where Walter is talking about Jimmy Hoffa while installing a light bulb, you can see the set and crew reflected on the metal part, including the audio coordinator with a boom mike.
Visible crew/equipment: When Arthur goes to Dragoon to ask for help, when Dragoon runs out of the hut to turn back into Merlin, on the left hand side of the screen you can see a camera crew in modern clothes. [Fixed in Netflix version]. (00:23:00)
Suggested correction: I don't see any crew. I'm watching it on Netflix. Perhaps they fixed or perhaps they edited it out after realizing the mistake. But they aren't there anymore.
Even if Netflix corrected the mistake doesn't mean the mistake is now invalid if the mistake existed in the original BBC One airing. Netflix is known to change or edit programs they stream (such as replacing soundtrack songs).
