Theatrical alchemy is eternally slippery.

Write what you know, says the adage, and that's exactly what playwright Ishy Din has done with his new play, Approaching Empty, now at the Kiln in Kilburn.

Time and a transfer haven't been kind to this well-meaning but surface-thin revival of Coming Clean, the 1982 Kevin Elyot play that is surely more poignant than is ever apparent here.

Confessions first: I fell asleep mid-way through Time Is Love/Tiempo es Amor, from too much time on trains and planes over the New Year. I was kindly allowed back for a second visit to the Finborough Theatre show, for a Sunday matinee, dosed with coffee and determined to concentrate fully. This was a good thing. The production's name attraction, Olivier Award-winner Sheila Atim, had previously seemed a minor part whereas her masterful performance (must one say mistressful these days?) as Rosa the stripper is a highlight of the piece.  

“Love Changes Everything”, as immortalised by Michael Ball, is the most enduring feature of Andrew Lloyd Webber, Don Black and Charles Hart’s 1989 musical – a moderate West End success, and a Broadway flop.

The scintillating, commercially bold season of Pinter one-acts at the theatre bearing his name plays a particular blinder with Pinter Five (★★★★★), from which I emerged keen to engage with its mystery and breadth of feeling all over again.

Will pride of place amongst theatre productions every year go in perpetuity to the work of Stephen Sondheim?

A tremendous year for American theatre on the London stage is resoundingly capped by Sweat, the Lynn Nottage Pulitzer prize-winner that folds the personal and the political into a collective requiem for a riven country.

Joe Hill-Gibbins’ uncompromising production of The Tragedy of Richard II hurtles through Shakespeare’s original text, stripping and flaying it so it is revealed in a new shuddering light. Narcissistic, petulant and indecisive, Simon Russell Beale’s Richard stumbles towards his downfall in a prison cell in which it is never clear what’s a figment of his paranoid imagination and what’s reality. 

With the politics of hate alive and well both sides of the Atlantic, this seems a good time to revive Tony Kushner and Jeanine Tesori's 2003 musical, which is set in Civil Rights-era Louisiana.
