London Assurance (originally titled Out of Town) is a six-act comedy by Dion Boucicault. It was the second play that he wrote, but his first to be produced. Its first production, from 4 March 1841 at the Theatre Royal, Covent Garden (by Charles Matthews and Madame Vestris's company) was Boucicault's first major success.
- Sir Harcourt Courtly, cultured 57-year-old fop
- Charles Courtly, his dissolute son
- Dazzle, Charles' equally dissolute companion
- Max Harkaway, country squire
- Grace Harkaway, Max's 18-year old niece, betrothed to Sir Harcourt
- Lady Gay Spanker, horse-riding virago
- Mr. Adolphus "Dolly" Spanker, her ineffectual husband
- Mark Meddle, lawyer
- Pert, Grace's maid
- Cool, Charles' valet
- James (Simpson)
- Martin, servant to the Courtlys
- Solomon Isaacs, moneylender, in pursuit of Charles
Charles and Dazzle arrive back at Sir Harcourt's London home after a night on the town, and manage to avoid Sir Harcourt with Cool's help—Sir Harcourt still believes Charles is a clean-living innocent. Max arrives to make the final arrangements for Sir Harcourt's marriage to Max's niece Grace—by arrangement, Sir Harcourt has financially helped Max in return for making Grace's inheritance contingent on her marrying Sir Harcourt (if she does not, it will pass to Charles). Sir Harcourt leaves and Dazzle bumps into Max, gaining himself an invitation to Oak Hall, Max's country house—a trip on which Charles will accompany him.
At Oak Hall, Grace explains to her maid Pert her acceptance of marriage to the aged Sir Harcourt and her view of love as an "epidemic madness". Charles and Dazzle arrive, and the former (not knowing of his father's marriage plans) immediately starts courting Grace. When his father arrives, Charles pretends, in the face of all evidence, that he is a man called Augustus Hamilton who merely bears a remarkable likeness to Charles and convinces his father for a time.
Lady Gay Spanker and her husband "Dolly" arrive, and Sir Harcourt immediately falls in love with the former. Grace begins to fall in love with Charles/Augustus in spite of herself. When Lady Gay interrupts their courtship, Charles easily persuades the lady to distract Sir Harcourt from marriage to Grace by apparently accepting his affections.
Charles leaves as 'Augustus', returning as Charles to tell Grace that 'Augustus' has been killed, to see if she really loves him, whilst Lady Gay and Sir Harcourt plan to elope together.
The elopement is frustrated by Max, Dolly and the local lawyer Meddle. Dolly challenges Sir Harcourt to a duel. Sir Harcourt realises he has been duped and resolves to release Grace from their marriage contract.
Max prevents the duel and Grace insists on going through with the marriage to Sir Harcourt, as a ruse to force Charles's hand. Charles's creditors catch up with him. Dolly forgives Gay and Sir Harcourt finds out his son's true nature as well as acceding to Charles's marriage to Grace.
The play is considered an intermediate point between the 18th-century comedies of Richard Brinsley Sheridan and Oliver Goldsmith on the one hand and Oscar Wilde’s The Importance of Being Earnest on the other.
The first major revival in the UK was the 1974 Royal Shakespeare Company production (directed by Ronald Eyre, with Donald Sinden as Sir Harcourt Courtly, Roger Rees as Charles, Judi Dench as Grace and Dinsdale Landen as Dazzle) which transferred to the Albery Theatre in London and toured to New York, where Eyre was nominated for a Broadway Tony Award for his directing and Sinden was the first recipient of the Broadway Drama Desk Special Award.
In 1976 the play was adapted for television by the BBC in the Play of the Month strand, with Anthony Andrews as Charles Courtly and Landen reprising his role of Dazzle. It also featured Judy Cornwell as Lady Gay, James Bee as her husband Adolphus, Charles Gray as Sir Harcourt, Jan Francis as Grace, Clifford Rose as Cool and Nigel Stock as Max.
A 1989 stage production at the Chichester Festival Theatre (directed by Sam Mendes and featuring Paul Eddington as Sir Harcourt) later transferred to London. Its cast also included John Warner as Adolphus. Other productions include one at the Royal Exchange Theatre Manchester in 2004, and a 2008 production at the Watermill Theatre in Bagnor, which toured to Guildford.
The play's popularity in America has continued through the decades, as it was produced in New York in 1869, 1905, 1937 and 1997.
The Royal National Theatre revived the play in March 2010, directed by Nicholas Hytner and featuring Simon Russell Beale as Sir Harcourt and Fiona Shaw as Lady Gay. A live performance was simulcast to cinemas around the world through their NTLive! program.
