Cloud Nine

Only eight more performances of this, the funniest and most stimulating night out in town, with Tim "Blackadder" McInnerney doubling as a colonial husband whose upper lip could not be stiffer and Cathy, the filthy-mouthed five-year-old in Caryl Churchill's tremendous comedy of sexual politics. Playing in repertory with Hurlyburly, David Rabe's savage portrait of Hollywood at its worst, dramatising the mutual mistrust and competitiveness underlying macho camaraderie. Rupert Graves and an excellent cast blast the brilliant drug-driven dialogue.

The Positive Hour

What is Emma doing with a man in a hood? Why is Miranda losing her patience with her New-Man husband? April de Angelis's witty, astute new play is a delightfully wry mix of men, money and S&M. Max Stafford-Clark's sharply acted production does it proud.

The Caucasian Chalk Circle

The Olivier has been triumphantly transformed into a theatre-in-the-round for this National/Theatre de Complicite co-production of Brecht's classic tale of justice. Juliet Stevenson is unsentimental and touching and the ensemble singing and playing gently builds to an evening of real power.
