Dutton then aged several decades to portray 'Morganhall', the eccentric barrister in John Mortimer's comic two-hander The Dock Brief, performed with Canadian actor Jonathan Hartman.

[23] In the early 1990s he turned from the theatre to comedy, performing an impressionist act on the stand-up circuit in London, and at this time began writing comedy shows for BBC Radio,[24] including Week Ending which he worked on with Peter Baynham, Richard Herring, Stewart Lee, Harry Hill, Ben Moor, Armando Iannucci, Harry Thompson, and Sarah Smith; and The News Huddlines, Roy Hudd's weekly topical sketch show.

During this time Dutton also dramatised and performed in six P. G. Wodehouse stories for BBC Radio 4, Ukridge, in which Griff Rhys Jones played the eponymous anti-hero, starring alongside Robert Bathurst.

The following year, in 1994, he was given his own series, Truly, Madly, Bletchley, which he wrote and starred in, along with David Battley, Liz Fraser, Simon Godley and Toby Longworth.

[24] Truly, Madly, Bletchley, produced by Dirk Maggs, was the first sketch show in the history of radio comedy to have been written by one person – apart from Harry Hill's Fruit Corner, which was being broadcast at the same time and which Dutton also performed in.

Other radio comedy shows Dutton performed in include Ian Hislop & Nick Newman's series Gush,[25] Mammon, and The Christopher Marlowe Mysteries.

At this period he was touring widely as a stand-up comedian, supporting Harry Hill in the West End, and performing with Al Murray, Jim Tavare and Jenny Eclair.

In 2009 Dutton wrote and performed two new radio comedy series, Inside Alan Francis, with fellow comedian and actor Alan Francis, and a new radio impressions show, The Secret World, produced by Bill Dare, in which Dutton performed alongside star impressionists Jon Culshaw, Lewis Macleod, Duncan Wisbey and Jess Robinson.

Dutton was also cast in many TV commercials, including playing the new Secret Lemonade Drinker in adverts with Ronnie Corbett, Frankie Howerd, and John McEnroe.

[6] As one of the lead writers on Chucklevision Dutton was commissioned to create and write a pilot for a new CBBC sitcom, Little Chucks, the adventures of Paul and Barry Chuckle as children, broadcast in 2010.

Other television appearances include the Emmy Award-nominated My Life as a Popat for ITV, The Sarah Jane Adventures, a Doctor Who spin-off for CBBC produced by Russell T Davies, Nuzzle and Scratch, a children's comedy series, and Scoop with Shaun Williamson.
