Bells (Blackadder) marks the first appearance of the Bob/Kate and Flashheart archetypes that appear again in "Blackadder Goes Forth". Rik Mayall, who played Lord Flashheart, allegedly designed the character's costume himself. John Lloyd has said that Mayall virtually rewrote his part to feature "loads of jokes", which annoyed the writers, Curtis and Elton. It was the only episode of the series to feature location filming, at Wilton House in Wiltshire. The music performed as Blackadder courts "Bob" is Vaughan Williams' "Fantasia on Greensleeves". In 1993, in conjunction with Comic Relief, this episode was given away free on cassette tape with boxes of
Blackadder: Back & Forth and photographs of historical scenes, edited to contain a Blackadder, accompanied by a full orchestral version of the Howard Goodall's "Blackadder" theme. The closing theme is a reprisal of the heroic version of the first series, with new lyrics sung by Giles Underwood; the lyrics appear onscreen with Blackadder's head as a bouncing ball. At Blackadder Hall in 1999 Lord Blackadder (Rowan Atkinson) is entertaining three guests on New Year's Eve. He informs them he has invented a time machine and wagers £10,000 each that he can bring back any item from history they ask for. Archbishop Melchett (Stephen Fry),
