The format of the Blackadder series was changed substantially after the BBC was displeased with the first series (The Black Adder (1983)). It was made as a standard studio sitcom with an audience, the characters' roles were redefined and the budget substantially trimmed.
Ben Elton proposed that Baldrick, who was the most intelligent of the main cast of the first series, become "the stupidest person in the history of human beings" to act as a foil to the now-smarter Blackadder.
The only location shooting for this season was the courting scene in Black-Adder II: Bells (1986) and the closing credit scenes; these scenes were shot over a couple of consecutive days in the gardens of Wilton House, Wiltshire. The rest of the season was shot on the filming stage, using a couple of standard sets (Blackadder's house and the Queen's court) and a couple of sets that would be built for each episode.
