Following
The Young Ones, Mayall continued to work on
The Comic Strip films. He also returned to standup, starring on
Saturday Live - a British adaptation of the American
Saturday Night Live - first broadcast in 1985. He and Edmondson had a regular section as "
The Dangerous Brothers", a pair of daredevils, who would perform comedy stunts on stage.
In 1985, Mayall debuted another of his comic creations. He had starred in the final episode of
The Black Adder in 1983 as "Mad Gerald". The series had proven expensive and a second series was not forthcoming until it was agreed that the budget would be cut and Elton would replace
Rowan Atkinson as co-writer (alongside
Richard Curtis). The "re-vamped"
Blackadder proved an enormous success thanks, in part, to the inclusion of a character named
Lord Flashheart, played by Mayall, in the series' first episode, "
Bells". Despite being on screen for mere minutes, Mayall's performance as the boisterous heart-throb Flashheart proved very popular and raised Mayall's public profile further.
The character was given a bigger part as Squadron Commander Flashheart in
Blackadder Goes Forth in 1989. A similar character, also played by Mayall, would appear in 2000's
Blackadder: Back and Forth under the guise of
Robin Hood.
In 1986, Mayall joined forces once more with
Planer, Adrian Edmondson and Elton to star in
Filthy Rich & Catflap as "Richie Rich" in what was billed as a follow-up to
The Young Ones. While he received positive critical reviews, viewing figures were poor and the series was never repeated on the BBC. In later years, release on video, DVD and repeats on UK TV found the series a
cult following. Mayall suggested the series did not last because he was uncomfortable acting in an Elton-written project, when they had been co-writers on
The Young Ones.
The same year saw Mayall achieve a number one hit in the
UK singles charts when he and his co-stars from
The Young Ones teamed up with Cliff Richard to record a new version of "
Living Doll" for the inaugural
Comic Relief campaign. Mayall played Rick one last time in the subsequent stage show and has supported the
Comic Relief cause ever since.
That year, Mayall appeared on the children's television series
Jackanory, on which well known-faces read children's stories. His crazed, anarchic portrayal of
Roald Dahl's George's Marvellous Medicine proved one of the series' most memorable performances. However, at the time, the BBC received complaints "with viewers claiming both story and presentation to be both dangerous and offensive."
In 1987, Mayall undertook his first major solo project as fictional [[Conservative Party (UK)|Conservative MP] Alan Beresford B'Stard in the sitcom
The New Statesman for
Yorkshire Television, written by
Laurence Marks and
Maurice Gran. The character was a satire of
Tory MPs present in the United Kingdom in the 1980s and early 1990s. The programme ran for four series - incorporating two BBC specials - between 1987-1994 and was a success both critically and in the ratings.
In a similar vein to his appearance on
Jackanory, in 1989, Mayall was the star of a series of "bit" shows for the BBC called
Grimm Tales, in which Mayall narrated
Grimm Brothers fairy tales, while puppets acted out the stories.
He also lent his voice to the
Playstation video game
Hogs of War.
