At his own request, Rik Mayall was not credited in the cast list (Mad Gerald was billed as "Himself").
This was Rik Mayall's first collaboration with Rowan Atkinson and it was noted that their work together took on a competitive edge; Mayall would dominate the set and preferred to rewrite his own lines. The competitiveness continued into their next two Blackadder appearances together, when Mayall played the overbearing womaniser, Lord Flashheart.
First Blackadder appearance of Rik Mayall (Mad Gerald) who appeared in Bells (1986) and Private Plane (1989) as Lord Flashheart and as Robin Hood in Blackadder Back & Forth (1999).
