Blackadder s the name that encompassed four series of a BBC One historical sitcom, along with several one-off instalments. All television program episodes starred Rowan Atkinson as anti-hero Edmund Blackadder and Tony Robinson as Blackadder's dogsbody, Baldrick. Each series was set in a different historical period with the two protagonists accompanied by different characters, though several reappear in one series or another, for example Melchett and Lord Flashheart.
