Plan E: General Hospital - S4-E5
Continuity mistake: After his interrogation, Darling is able to run out of the doctor's office (albeit hobbled by the chair he is tied to) despite having been shot in the foot and having been seen visibly limping earlier.
Plan B: Corporal Punishment - S4-E2
Continuity mistake: Black Adder shoots the pigeon, and the feathers fly everywhere. One feather lands on Black Adder, just above his ear. In the next shot, the feather has moved up, on the other side of his side-part, towards the top of his head.
Continuity mistake: When Blackadder and the other soldiers are about to go "over the top", you can see two other soldiers standing behind Darling. They are presumably in the upper part of the trench. When Blackadder blows his whistle, you see all the soldiers climb onto their ladders and then start to rush over, side-by-side. In the next shot, when we see the soldiers emerging from the trench in slow motion, the other two soldiers are still back in the trench waiting for Darling to climb out before they move, as the two shots were filmed in two different studios.
Continuity mistake: When Blackadder, Baldrick and George are out in the no man's land, Blackadder screams and Baldrick asks why. Blackadder answers he put his elbow in a blob of ice cream while looking at Baldrick. When it cuts he is looking straight forward instead. (00:22:20)
Continuity mistake: When Blackadder's plane is shot, we see the bullets hit the side. In the next shot of the plane, not only is the side intact, but fuel is coming out of the bottom.
Continuity mistake: Blackadder chucks up George's helmet, and it gets riddled with bullet holes. When the helmet comes down, it comes down at an angle, revealing that it had been passed down. (00:04:30)
Continuity mistake: When Flasheart hits Edmund with the gun, he swings his arm to the right, but Edmund falls to the left.
