Visible crew/equipment: During the general's speech about how Blackadder is the person to organise a concert party, look at the entrance to the trench. In one shot you can see a crew member moving a giant cloth. You see mostly the movement, but you can catch a glimpse of the crew member's face. (00:06:50)
Blackadder (1986)
1 visible crew/equipment mistake in Plan C: Major Star
Plot hole: In 'The Foretelling', it is said that Richard IV reigned for "13 glorious years" with a caption showing 1485-1498. 'The Black Seal' starts on St. Junipers' Day, 1498, but Blackadder spends 12 months locked up with Mad Gerald. So when the Royal Family are finally murdered it is actually 1499.
[Blackadder puts the phone down.]
Baldrick: Who was that?
Blackadder: Strangely enough Baldrick, that was his Holiness Pope Gregory IX, inviting me to join him for drinks aboard his steam yacht, the Saucy Sue, currently wintering in Montego Bay, with the England cricket team, and the Balinese Goddes of Plenty.
Baldrick: Really?
Blackadder: No, not really. I've been ordered to HQ - no doubt means that idiot General Melchett is about to offer me an attractive new opportunity to have my brains blown out for Britain.
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: Who played the balladeer and why was Blackadder trying to kill him?
Answer: Tony Aitken played the Balladeer. Blackadder wants to kill him because he annoys him and usually sings songs about what a fool he is.
