While watching a preview tape of highlights from Enfield's programme, Whitehouse and Higson were inspired to create a rapid-fire delivery comedy series, which would evolve into "The Fast Show" (when shown in the United States on BBC America, the show was titled "Brilliant"). Whitehouse's characters included:  An online series of "The Fast Show" commissioned by Fosters led to six weekly episodes launched on 10 November 2011. In 2001 and 2002, Whitehouse wrote and performed in two series of the BBC comedy drama "Happiness", in which he played a voice-over actor with a mid-life crisis. Whitehouse wrote, produced and appeared with Chris Langham in the 2005 comedy drama "Help", also for the BBC. In this series he took 25 roles, all patients of Langham's psychotherapist (except one, who is Langham's psychotherapist's psychotherapist). The pair's collaboration resulted in Whitehouse taking the witness stand on 24 July 2007 in the trial of Langham, in regard to the charge of holding explicit images and videos of minors. Langham claimed he downloaded this material as research for a character in the second series of "Help", but Whitehouse's testimony only partially corroborated this explanation. Whitehouse appeared in the BBC sketch series "Harry & Paul" (formerly "Ruddy Hell! It's Harry and Paul"), starring alongside Harry Enfield. Whitehouse starred alongside Charlie Higson in the BBC2 comedy series "Bellamy's People", with the first episode broadcast on 21 January 2010. The comedy evolved from the BBC Radio 4 program "Down the Line". The show originally had the working title of "Bellamy's Kingdom". In October 2014, Harry Enfield and Whitehouse returned to the characters of Frank and George in a sketch for Channel 4's testicular cancer awareness comedy series "The Feeling Nuts Comedy Night". In 2015, his sitcom "Nurse", based on his Radio 4 series of the same name (see below), debuted on BBC2 on 10 March. In August 2015, Whitehouse, alongside Enfield, in celebration of their 25-year partnership, presented "An Evening With Harry Enfield and Paul Whitehouse". In June and July 2018 Whitehouse appeared with his long time friend and fellow comedian Bob Mortimer in a BBC2 six part comedy series, "". The two friends, who both suffer from heart conditions, share their thoughts and experiences while fishing at a variety of locations around the UK. Whitehouse and Charlie Higson produced and appeared in a spoof phone-in show "Down the Line" on BBC Radio 4.
