At the dinner party at the beginning, a portrait of Captain Blackadder from Blackadder Goes Forth (1989) is positioned on the wall behind the present Blackadder.
Was shown at SkyScape attraction at London's Millenium Dome eight times a day for the whole of 2000.
Brian Blessed, Elspet Gray and Robert East were originally going to reprise their roles from Blackadder (1982). The scene would have been Blackadder and Baldrick arriving at Bosworth field and killing Henry Tudor with the time machine, however the scene was later changed to the battle of Waterloo as Blessed was unable to reprise his role of Richard IV.
The budget for this mini-movie allowed for far more elaborate sets than had been seen since the first Blackadder (1982). In particular, the set for "Queenie" Elizabeth's court - a small room, barely capable of holding 10 people in Blackadder II (1986) - is a large, richly-decorated space in this film, filled with dozens of courtiers. Queenie's costume is also far more elaborate in this film.
In addition to playing the various incarnations of Melchett, Sir Stephen Fry reprises his role as the Duke of Wellington, though the character bears little resemblance to the version who appeared in Blackadder the Third (1987).
Jennie Bond: the voice of the Royal Reporter in the ending scene was the BBC Royal correspondent from 1985 to 2003.
Colin Firth: as William Shakespeare. His casting is likely an allusion to his role as Lord Wessex in Shakespeare in Love (1998).
