Playwright Willy Russell in his Liverpool office in 1988. He worked as a hairdresser before becoming a playwright and gave his heroine the same job. ‘I didn’t set out to write an autobiographical play, but the parallels between Rita and me seem glaring now,’ he said. ‘I left school with one O-level and went back to get the education I’d not had.’

The original version ... Julie Walters as hairdresser Rita and Mark Kingston as alcoholic lecturer Frank in the first production of the play, commissioned for the RSC, at the Warehouse, London, in 1980. Walters won an Olivier award for her performance, and the Pygmalion-esque play won comedy of the year.

Russell himself adapted the play for the film version, directed by Lewis Gilbert and starring Julie Walters and Michael Caine, in 1983. Gilbert and Russell later reunited on Shirley Valentine.

Larry Lamb and Laura Dos Santos star in a revival at the Menier Chocolate Factory, London, in 2010. Frank and Rita discuss several works of literature: Frankenstein, Howards End (‘crap!’ says Rita) and Yeats (‘the wine lodge?’ she asks). Dos Santos had starred in the 2009 radio version of the play.

When it transferred to Trafalgar Studios, Tim Pigott-Smith took on the role of Frank, pictured here with Laura Dos Santos as Rita, 2010.
