Visible crew/equipment: When Blackadder calls for Baldrick and asks for a raw turnip, as Baldrick enters, you can see some shadow moving on the left of the screen. It's not Baldrick's shadow and there's certainly no one else in the room that could make that shadow. (00:13:55)
Continuity mistake: When Blackadder, Queenie and Nursey are all comforting Melchett, there is a shot from the side view of Melchett, he is holding his head with his left hand.

Revealing mistake: When Percy is holding the 'Green' in his hands, light of the green reflects on the wall behind Blackadder. However the way Percy is holding the 'green' in front of Blackadder, Blackadder's shadow should be on the wall behind him, but it isn't. It's obvious green lighting is used to light up the back wall.
