With a budget of over £3 million, 'Clarissa' was filmed from 29 April until 19 July 1991. Locations included several large country houses (one in the north of England, another near Stratford, and a third in Hampstead). Some exteriors were shot outside The Inns of Court in London but much of the filming was done at London's Ealing Studios, where a three-storey Georgian house was specially constructed for the series.
