Douglas Argent, who has died aged 89, was a prolific producer and director who scored hits with Till Death Us Do Part, Steptoe and Son, Fawlty Towers and Spike Milligan's Q8 and Q9 series – all with humour that pushed the boundaries of TV comedy.
He was gifted the second series of Fawlty Towers to produce in 1979. The creation of John Cleese and Connie Booth – who had divorced since the first run, four years earlier – went on to top a British Film Institute list of the 100 best TV programmes, as voted for by industry professionals. Argent modestly insisted that its success lay in the writing. However, producers guide all those working on their programmes and his track record was impressive, particularly in the field of comedy.
Argent was born in Bexleyheath, Kent, and his parents ran ironmonger's shops.
