Character mistake: After firing Percy and Baldrick, Edmund says to Baldrick that he'll probably go back to shovelling dung in the gutter where Edmund found him. In the pilot episode The Foretelling, Edmund actually met Baldrick when Baldrick was pouring a drink for Edmund.
Continuity mistake: In Back and Forth, the 'modern' Edmund makes off with the helmet we saw Georgius put on the wall. But in the next shot of the Roman Blackadder and Georgius, the helmet is still where Georgius left it.
Plan B: Corporal Punishment - S4-E2
Blackadder: I remember Massingbird's most famous case - the Case of the Bloody Knife. A man was found next to a murdered body. He had the knife in his hand, thirteen witnesses had seen him stab the victim and when the police arrived he said 'I'm glad I killed the bastard.' Massingbird not only got him off, he got hom knighted in the New Year's Honours list, and the relatives of the victim had to pay to get the blood washed out of his jacket.
Trivia: The original footage of the famous final scene was very disappointing. The set was small, and the cast only charged forwards a small distance before unconvincingly falling over when "shot". The scene was saved in editing, slowing down the video and audio enormously, and fading to an empty shot of no-man's land, then the poppies. The final result has been described as one of television's most powerful endings.
Question: Many times during the series, Lieutenant is pronounced as 'Left-tenant'. Why?
