Tim Firth, whose adaptation of his Calendar Girls screenplay won last year’s Whatsonstage.com Award for Best New Comedy, returns to the West End next month with his latest play, Sign of the Times. Matthew Kelly and ShamelessGerard Kearns star in the two-hander, which opens on 11 March 2011 (previews from 7 March) at the Duchess Theatre, where it’s initially booking to 28 May.

Frank Tollit (Kelly) has put up giant letters on the sides of buildings for over 25 years. From 40-foot yellow IKEAs to five-foot red COMETs, Frank has done them all. It’s been his talent… but not his ambition. That involves a very different sort of letters – literary ones. But a lifelong lack of success is driving him to the edge. However, not even in one of his wildest plots could Frank have dreamed that salvation would turn up in the shape of a clumsy teenager (Kearns) on work experience.

Originally written in 1991 as a one-act play called Absolutely Frank for Scarborough’s Stephen Joseph Theatre under Alan Ayckbourn, the full-length version of Sign of the Times toured the UK last year with Stephen Tompkinson and Tom Shaw. Firth’s other credits include Neville’s Island, The Safari Party and Olivier Award-winning Madness musical Our House on stage; and Calendar Girls, Blackball, Kinky Boots, Money for Nothing and Preston Front on screen.

Sign of the Times is directed by Peter Wilson, with design by Morgan Large (nominated in the 2011 Whatsonstage.com Awards for Flashdance), with lighting by Tony Simpson and sound by Gareth Owen.

Matthew Kelly won the 2003 Olivier Award for Best Actor for Of Mice and Men. His many theatre credits since have included Waiting for Godot, Who’s Afraid of Virginia Woolf?, Troilus and Cressida, Comedians and the musicals Spamalot and Lend Me a Tenor.

Best known as Ian Gallagher from Shameless and Ryan in Ken Loach’s film Looking for Eric, Gerard Kearns’ stage credits include A Thousand Yards, Hanky Park and Borstal Boy. Sign of the Times marks his West End debut.

Currently at the Duchess, Howard Goodall’s musical version of Erich Segal’s Love Story, starring Michael Xavier and Emma Williams, finishes its run on 28 February 2011.
